GCSE Physics

Sound Answer 1

You said: "A is higher in pitch and louder than B".
Here are the waves again:

Sound A
Sound B

Nearly, but not quite right!

Sound B has a higher frequency (there are more waves in a given time) so B is actually higher in pitch than A.

However, you were right that sound A is louder than B, as its waves have more energy (a larger amplitude)
