General properties of waves — practice question

The diagram depicts a section of a diffracted wave pattern. The wavelength and the gap size are altered to create a semicircular diffracted wave pattern. Which row gives the required semicircular diffracted wave pattern?

  • Agap in barrier: larger; wavelength: same
  • Bgap in barrier: larger; wavelength: smaller
  • Cgap in barrier: same; wavelength: larger
  • Dgap in barrier: same; wavelength: smaller
