- 1What is a transverse waveA transverse wave is when the vibrations are at a right angle to the direction of the wave
- 2What is a longitudinal waveA tranvese wave is when the vibrations are parrallel to the direction of the wave
- 3What type of wave is sound and siesmic p wavesLonitudinal waves
- 4What is frequency?Frequency is the number of waves per second/ number of waves produced in a second (hertz)
- 5What is the equation for speedspeed = distance over time
- 6How do you calculate wave speedwave speed
= frequency x wavelenghth
= f x ℷ - 7What is the speed of sound in air330 m/s
- 8What is the speed of light in air3 x 10^8 m/s
- 9How do you work out the power of the lensPower of lens = 1 ÷ f
F = focal lens - 10What is the focal lengthThe focal length is the length at which a lens can focus
- 11What is a convex lensA lens that is round, and can focus on one screen
- 12Wha is a diverging lensA lens that is concaved, the rays diverge and it can be focussed on a screen
- 13What is the main difference between a diverging lens and a convex lensA diverging lens creates a virtual image and can't be focused on a screen however a convex lens creates a real image that can be focused on a screen
- 14Give an example of a real imageA cinema screen
- 15Give an example of a virtual imageA mirror image
- 16What is the law of reflectionAngle of incidence = angle of reflection
- 17What are the primary colours of lightRed, Blue, Green
- 18What colour does blue and green makeCyan
- 19What colour does blue and red makeMagenta
- 20What colour does red and green makeYellow
- 21What is ultrasoundUltrasound is a sound wave with a frequency above 20 kHz, which is too high for human hearing
- 22What is InfrasoundInfrasound is a sound wave with a frequency below 20hz, which is too low for human hearing
- 23What is a reflected waveA wave that bounces off
- 24What is a refracted waveA wave that passes through a new medium/ material but changes the direction in which it is traveling
- 25What is a transmitted waveA wave that passes through a material/ medium is not absorbed or reflected
- 26What is an absorbed waveA wave that disappears as the energy it is carrying is transmitted to the material
