Sometimes reflection of sound can be o in
desirable can you give any example

Answer 1

Every time I go to the beach, I am fascinated by all of the colored pebbles I find. Tiny stones of pink, yellow, blue, and violet flash under the shallow waves. I can't resist the urge to collect them, and I usually go home with a pocketful of my favorite pebbles. But once I get them washed and dried, I am often disappointed with how dull they all appear. Where did their vibrant colors go? What happened to their glossy sheens? I should have known from the beginning that the dry pebbles would look different because of the effects of diffuse reflection.
