5054General properties of waves

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?

  1. Awavelength of wave in region P: larger; speed of wave in region P: faster
  2. Bwavelength of wave in region P: larger; speed of wave in region P: slower
  3. Cwavelength of wave in region P: smaller; speed of wave in region P: faster
  4. Dwavelength of wave in region P: smaller; speed of wave in region P: slower
