1
Which is the correct description of a transverse wave?
Answer & explanation
Correct: option B
Transverse waves have particles vibrating at 90° to the direction of energy transfer.
2
Which is a longitudinal wave?
Answer & explanation
Correct: option C
Sound is the standard longitudinal example. All EM waves and water ripples are transverse.
3
What is transferred by both transverse and longitudinal waves?
Answer & explanation
Correct: option C
All waves carry energy without carrying matter. They can also carry information.
4
A loudspeaker emits a sound. Which best describes what happens to the air particles in front of it?
Answer & explanation
Correct: option B
Sound is longitudinal: air molecules oscillate along the wave direction, creating compressions and rarefactions.
5
Which statement is true about light?
Answer & explanation
Correct: option B
All EM waves, including light, are transverse and need no medium.
6
Which apparatus would a teacher use to demonstrate transverse water waves in a UK GCSE lab?
Answer & explanation
Correct: option B
A ripple tank produces controlled water ripples that can be timed and measured for AQA RP8.
