Q

How should wavelength be measured?

A

It can be measured from one point on one wave to the same point on the next wave but should (as proper practice) be measured from crest to crest

Q

Define amplitude

A

The distance between the centre line and the crest of the wave or between the centre line and the trough

17
Q

What is the trend between the amplitude of the wave and the amount of energy it carries?

A

The bigger the amplitude the more energy the wave is carrying

18
Q

What is the trend between the amplitude and the volume of sound produced by the wave

A

The larger the amplitude the louder the sound

19
Q

What is the speed of sound in air

A

340 ms-¹

Q

INFORMATION CARD

A

When light passes from air into glass it bends towards the normal. When it passes from glass back into air it bends away from the normal.
