Waves.
Cards in this deck (17)
- 1What is a transverse wave?A type of wave that:
- Moves perpendicular to the direction of energy flow
- Doesn't require particles to move
- Have peaks and troughs - 2What is a waveA vibration or oscillation that transfers energy from one place to another without the medium moving itself.
- 3What is the Doppler effectThe change in the frequency of a wave cause by the source of the wave moving away from the observer.
- 4What is red shift?Light from really far away has lower frequencies because all of the colours have shifted to the red end of the spectrum, this is called red shift.
- 5What is a longitudinal wave?A type of wave that:
- Moves parallel to the direction of energy flow
- Moves through compressions and rarefactions
- require particles to move - 6What is a mechanical wave?A type of wave that does require particles to move
- 7What is an electromagnetic wave?A type of wave that doesn't require particles to move
- 8What type of wave is a sound wave?Mechanical and longitudinal
- 9What type of wave is a light wave?Electromagnetic and transverse
- 10What is the equation for a wave?V = f x λ
f = V / λ
λ = V / f
λ = wavelength
f = frequency
V = velocity - 11What is the angle of refraction equal to?The angle of incidence
- 12What does amplitude tell us about sound waves?How loud the sound is
- 13Rule for reflection?The angle of incidence is equal, but opposite, to the angle of reflection
- 14What is refraction?When the medium changes density causing the light wave to change speed.
- 15What happens to light waves when the medium changes density?They refract. Less dense to more dense causes the wave to slow down, meaning the angle of incidence is smaller than the angle of reflection. More to less dense, the angle of incidence is greater than the angle of reflection.
- 16What is diffraction?Waves spreading out and curving to fit through a gap.
- 17Order of the electromagnetic spectrum?Radio waves
micro waves
infra red
visible light
ultra violet
x rays
gamma rays
