Microwaves from a transmitter are directed normally at a metal plate, which reflects the waves back towards the transmitter. Use a narrower metal plate with the two plates from before to make a pair of slits and use the receiver to test for points of cancellation and reinforcement, where the microwaves from the two slits overlap. A ripple tank may be used to show wave properties such as reflection, refraction and diffraction. This shows that the strength of the microwaves decreases with distance. Under no circumstances is content to be used for commercial gain. ∴ The Speed of the waves, c=Distance travelled in one cycle/time taken for one cycle.

Period of a wave is the time for one complete wave to pass a point. Use to metal plates to make a narrow slit and show that the receiver detects microwaves that have been diffracted as they pass through the slit. Please check the specific areas you need with your exam board. Frequency is double that of the first figure, but now half the wavelength. the two waves cancel each other out. this is rilly gud…i can now get to do revision in a simple way, Guys what about A-Level Physics rules and equations, that will be really helpful. The longer the wavelength, the more spread out the waves are. 180° or π radians if the two particles are separated by an odd number of nodes. If the string is plucked more vigorously, the string vibrates in a more complicated way and the note produced contains other frequencies, as well as the the frequency produced when the string is plucked gently. GCSEs & IGCSEs When a guitar string is plucked, the sound produced depends upon the way the string is plucked. S.I.

FOUNDATIONS OF PHYSICS: Physical Quantities: Physical quantities have a numerical value and a unit. The narrower the gaps, the more spread out the waves are. The angle between the reflected wave front and the surface is the same as the angle between the incident wave front and the surface. When they are in phase, they reinforce each other to produce a large wave as shown in this figure: A ¼ of a cycle later, the two waves have each moved a quarter of a wavelength in opposite directions. Post was not sent - check your email addresses! All particles vibrate at the same frequency, Amplitude varies from zero (nodes) and a maximum. They are in anti-phase and so they cancel each other out, as shown below: A further quarter of a cycle, the two waves are back in phase, the resultant is again a large wave as shown in the first diagram. The frequency of a wave is the number of cycle of vibrations or particles per second. The simplest stationary wave pattern as shown below, consists of a point of no displacement at both ends, called nodes and a point of maximum amplitude midway between the adjacent nodes, called anti nodes. Straight waves directed at a certain angle  to a hard flat surface (reflector) reflect off at the same angle. Sound waves in air are created by making a surface vibrate so it sends compression waves through the surrounding air. All resources are updated for the latest AQA Physics specification. If the vibrations change from one plane to another, the waves are un-polarised. We can measure the diameter of an object keeping it in between the 2 jaws. The reflected waves and the waves from the transmitter form a stationary wave pattern. Cambridge International AS and A Level Physics (9702) Other Resources.

However a bigger dish also reflects the radio waves to a smaller focus because it diffracts the waves less. this week's promoted video from Physics Trek . physics revision notes for ordinary level Sep 29, 2020 Posted By Erskine Caldwell Media TEXT ID b41d07bc Online PDF Ebook Epub Library pressure 2 thermal free cie a level physics 2019 2021 revision notes created by teachers for the 9702 syllabus find more resources made by … The dish therefore needs to be aligned more carefully than a smaller dish, When a crest meets a crest, a super-crest is created (the two waves reinforce each other), When a trough meets a trough, a super-trough is created (the two waves reinforce each other). They are written for the AQA exam board but should still be useful for all other exam boards, including Edexcel, and OCR A and B. Resources for top A1 candidates taking the 2020 Singapore-Cambridge GCE O Level exam. Because they move slower in the shallow water, the wavelength is slower in the shallow water and therefore it changes direction. The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of physics, and a strong emphasis on advanced practical skills. IF the wave fronts approach at an angle to the boundary, they change direction as well as changing speed. The notes available here are great for revision and studying on the go. 15 September 2019 : Cambridge International AS and A Level Physics (9702) notes and other quick revision resources are now available.

Complete AS level Physics Notes Cambridge International AS and A Level Physics builds on the skills acquired at Cambridge IGCSE (or equivalent) level. – a revision checklist for each topic – information and advice in revision planning. Using this diagram, the wave passes through the first fence due to the position of the slit in the fence. Occurs when waves spread out after passing through a gap or round an obstacle. If un polarised light is passed through two Polaroid filters, the transmitted light intensity changes if one Polaroid is turned relative to the other one. Sound waves in air are created by making a surface vibrate so it sends compression waves through the surrounding air. The light ray changes direction when it crosses the glass boundary due to light travelling slower in glass than in air. Energy b. Sound waves, seismic waves and waves on strings are known as mechanical waves. Show that if the slit is made wider, diffraction occurs less. A-Level Physics Revision section of StudyWise. General physics 1.1 length and time 1.2 Speed, velocity and acceleration 1.3 Mass and weight 1.4 Density 1.5 Forces a. Vibrating electric field generates a vibrating magnetic field, which also generates a vibrating electric field further away. Length of the rope is equal to one full wavelength, Amplitude= 0 at nodes, therefore no energy at the nodes. Effects of forces b. If the phase difference changed at random, the points of cancellation and reinforcement would move at random, and no interference pattern would be observed. The positions where no signal is found are where the nodes occur, they are spaced at intervals of half a wavelength. Because the nodes and anti-nodes are in fixed positions, no energy is transferred in a freely vibrating stationary wave pattern. Transverse waves are plane-polarised if the vibrations stay in one plane only. Waves that pass through a substance are vibrations which pass through that substance. PHYSICS IGCSE 2012 EXAM REVISION NOTES By Samuel Lees and Adrian Guillot 1. Own a smartphone, laptop or tablet? An example of refraction is shown when water passes a boundary of shallow to deep water at angle to the boundary. Place the receiver in the path of the microwave beam from transmitter. The points where there is no displacement (the nodes) are fixed in position throughout. When waves pass across a boundary at which the wave speed changes, the wavelength also changes. Effect can be seen in a ripple tank when straight waves are directed at a gap. Amplitude= maximum at the anti-nodes, so there is a maximum energy at the anti-nodes. The amplitude of a vibrating particle in a stationary wave pattern varies with positions from zero at a node to a maximum amplitude at an anti-node. 22 April 2020 : All content for Cambridge International AS and A Level Physics (9702) has been updated. Points of cancellation are created where a crest from one dipper meets a trough from the other dipper. As the waves are continuously passing through each other at a constant frequency and a constant phase difference, cancellation and reinforcement occurs at fixed positions. If the frequency of the waves along the ropes from either end is raised steadily, the pattern from the previous diagram disappears and a new pattern is observed with two equal loops along the rope. Stationary waves are formed on a rope if two people send waves continuously along a rope from either end.
