- 1what is a wave?a wave is a transfer of energy.
- 2what are the two types of waves?transverse waves and longitudinal waves
- 3what are transverse waves?in transverse waves the oscillations are perpendicular (at 90 degrees) to the direction of energy transfer.
- 4what are longitudinal waves?in longitudinal waves the oscillations are parallel to the direction of energy transfer.
- 5give an example of a transverse waveall electromagnetic waves
e.g light - 6give an example of a longitudinal wavesound waves
- 7what is the equation for wave speed?wave speed= frequency x wavelength
- 8what three things can happen when a wave meets a boundary between two materials?the wave can be absorbed by the second material, the wave can be transmitted through the second material, the wave can be reflected.
- 9what are all the waves in the electromagnetic spectrum?radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays
- 10what electromagnetic wave has the lowest frequency?radio waves
- 11what section of the electromagnetic spectrum can humans see?visible light
- 12what is the amplitude?the maximum displacement of a point on the wave from its undisturbed position.
- 13what is the frequency?the number of complete waves passing a certain point per second.
- 14what is frequency measured in?hertz (HZ)
- 15what equation do you use to find the period of a wave?period=1/frequency
- 16what equipment is needed for the ripple tank practical?a lamp, signal generator, meter ruler, water, desk, white paper
- 17outline the ripple tank experiment.1)using a signal generator attached to the dipper of a ripple tank you can create waves.2)dim the lights and turn on the lamp. You should see the waves as shadows on the paper below the tank.3)the distance between each shadow is the wavelength, measure the distance and use the wave equation.
- 18what is refraction?when waves change direction at a boundary.
- 19what do ray diagrams do?ray diagrams show the path of a wave.
