GCSE AQA Physics - Waves

What do waves transfer?

• Energy and Matter

• Energy but not Matter

• Matter but not Energy

• Neither Energy nor Matter

The amplitude of a wave is:

• The distance between the same point on two adjacent waves

• The maximum displacement of a point on the wave from its undisturbed position

• The number of complete waves passing a certain point per second

• The amount of time it takes for a full cycle of a wave to pass a point

The wavelength of a wave is:

• The distance between the same point on two adjacent waves

• The maximum displacement of a point on the wave from its undisturbed position

• The number of complete waves passing a certain point per second

• The amount of time it takes for a full cycle of a wave to pass a point

Formula for the period of a wave:

• Period (T) = 1/Frequency (f)

• Period (T) = Frequency (f) x Wavelength (m)

• Period (T) = Wavelength (m) x Amplitude (a)

What is Frequency measured in?

• Hertz

• Watts

• Volts

• Vibrations

Which way do the oscillations of a Transverse wave travel?

• Perpendicular to the direction of energy transfer (side to side)

• Parallel to the direction of energy transfer (forwards and backwards)

Two examples of Transverse Waves:

• Sound waves

• Shock waves

• Water waves

• Electromagnetic waves (e.g. light)

Formula for Wave Speed:

• Frequency x Amplitude

• Frequency x Wavelength

• Wavelength/Frequency

• Wavelength/Amplitude

• Amplitude x Wavelength

Two examples of Longitudinal Waves:

• Sound Waves

• Waves on a string

• Light Waves

• Shock Waves
