What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to sound. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on sound, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Calling sound a transverse wave.
- Saying sound can travel through a vacuum.
- Saying sound travels fastest in gases, by analogy with light.
- Swapping loudness and pitch, or amplitude and frequency.
- Forgetting to halve the distance in an echo or sonar calculation.
- Using the whole reflected path when the question asks for the gap between two sounds.
- Quoting the range of hearing as 20 Hz to 20 kHz and then calling 15 kHz ultrasound.
- Adjusting an experimental speed towards the textbook value rather than reporting what the measurement gives.
Revise it first
