Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
When a wave is reflected from a plane surface, the angle of reflection equals
the angle of incidence
90°
zero
the angle of refraction
2.
A wave slows down on entering a new medium at an angle. It
does not bend
reflects
bends away from the normal
bends towards the normal
3.
Which quantity does NOT change during refraction?
speed
wavelength
frequency
direction
4.
Diffraction through a gap is greatest when the gap is
much larger than the wavelength
about the same size as the wavelength
very far from the source
covered
5.
A wave of frequency 10 Hz changes speed from 20 cm/s to 15 cm/s. The new wavelength is
1.5 cm
2.0 cm
0.75 cm
3.0 cm
6.
Why can sound travel round a corner when light cannot?
light is longitudinal
sound is a transverse wave
sound is faster
sound has a longer wavelength so diffracts more
