In the figure shown, the directional change of the light waves occurs because O A. light waves travel faster through air than water O B. light waves travel faster through water than air O C. waves carrying less energy produce light with lower intensity OD. the angle of reflection of waves always equals the angle of incidence​

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.
