waves

transverse waves have oscillations _________ to the wave motion

longitudinal waves have oscillations ________ to the wave motion

what best describes wavelength?

• maximum displacement of a particle

• the distance between two crests/troughs

• a wave

• number of waves

What best describes amplitude of a wave?

• length of a wave

• number of waves

• it does not exist

• maximum displacement from the equilibrium position

what best descibes frequency?

• number of complete waves passing through a given point per second

• time it takes for one complete wave to pass

• length of a wave

• speed of a wave

select the correct wave equation

• speed = frequency / wavelength

• speed = frequency x wavelength

• speed = distance / time

• speed = frequency x time

what three effects are observed when light rays refract?

• speed is changed

• wavelength can increase / decrease

• waves can change direction

• frequency can change

• amplitude can increase / decrease

when light splits into a range of colours called spectrum, what is the effect called?

• refraction

• diffusion

• diffraction

• dispersion

White light, {more than 1 options may be correct}

• is a part of electromegnatic spectrum.

• contains several waves of different wavelengths, frequencies which are vissible to humans.

• is an example of longitudinal waves.

• is very dangerous.

Maximum pressure change gives us the ________ of the sound wave

• Frequency

• Amplitude

• Wavelength

• Time period
