Which two options are examples of waves diffracting? A. Light bending as it travels through glass
OB. Sound amplified when passing through an open door
C. Your image in a mirror
I D. Water waves passing through a gap in a barrier
Help!! Fast please thank you for your time :)

B and D

Explanation:

Diffraction refers to the bending of waves either around an obstacle or through a gap.

A is not diffraction because although it involves the bending of light, it is due to travelling between mediums instead of bending around an obstacle or through a gap, (A is referring to refraction).

B is an example of diffraction because it is referring to the bending of the sound waves as it passes through a gap (a door) which is why it is amplified.

C is not an example of diffraction as the light waves do not bend, they simply bounce back from the mirror surface to form the image (reflection).

Finally, D is diffraction because the waves are passing though a gap in a barrier and will bend as a result due to diffraction.

Hope this helped!
