10 what is the main difference between refraction and diffraction? a refraction is a phenomenon that affects light; diffraction is a phenomenon that affects sound. b refraction involves the bending of light; diffraction involves the bending and spreading of light. c refraction usually happens in the atmosphere; diffraction usually happens closer to the earths surface. d refraction involves changes to the density of light; diffraction involves changes to the speed of light.
Answer
Brief Explanations:
Refraction is the bending of light as it passes from one medium to another due to a change in speed. Diffraction is the bending and spreading of light around obstacles or through openings. Option A is incorrect as both can affect light (and other waves like sound). Option C is wrong as there's no such strict location - based division. Option D has the concepts reversed (refraction is due to speed change, not density change of light in the way described).
Answer:
B. Refraction involves the bending of light; diffraction involves the bending and spreading of light.
