The diagram shows a water wave in a ripple tank being refracted at the boundary between region P and region Q. How does the wave in region P compare with the wave in region Q?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Awavelength of wave in region P: larger, speed of wave in region P: faster

Bwavelength of wave in region P: larger, speed of wave in region P: slower

Cwavelength of wave in region P: smaller, speed of wave in region P: faster

Dwavelength of wave in region P: smaller, speed of wave in region P: slower

✓ Correct answer

A: wavelength of wave in region P: larger, speed of wave in region P: faster
