Can someone please explain me the following objective of the Physics Syllabus of 2016 :
# Topic : Properties of waves

objective: Describe how wavelength affects diffraction at an edge

I can't find anything related to this in any of my physics textbooks

I will by tom :)

Hi, I am looking for Speaking Topics for 2016 for Riyadh, KSA.
Here's my guess on the bullet points for TV Violence:
  • How do you feel when you watch something violent on TV
  • How do other people you know react to violence shown on TV
  • What are the negative aspects of broadcasting violence on the TV
  • Should TV Violence be totally banned or should there be restrictions on the amount of violence that maybe safe?
  • What role can governments play in controlling what is shown on TV?
Please post topics as you find out and I can add questions for you all to practice.

this refers to simple diffraction through a gap.
When the wavelength (distance between two wavefronts)is greater then the aperture (gap between the barriers) then the wave will not pass through the gap.
When the wavelength is smaller then the aperture then there is little diffraction (only at the edges).
When the wavelentgh is the same size as the aperture then there is maximum diffraction.

Check this link.The pic will surely clearify your ideas.

Hope this helps :)
