Question

does sound follow the same laws of reflection as the light does ? explain !

when is sound is reflected from a distance object and eco is produced at the distance between the reflecting surface and the source of sound production remain the same to you hear eco sound on a hotter day ?

give two practical application of reflection of sound wave ? ​

Answer 1

Answer:

Yes, sound follows the same laws of reflection as that of light because, (i) Angle of incidence of sound is always equal to that of angle of reflection of sound waves. (ii) The direction in which sound is incident, the direction in which it is reflected and normal all lie in the same plane.

Answer 2

✔ Answers

___________________

a) Sound is reflected in the same way as the light . show the sound follow the same law of reflection as light does for example ;

• the incident sound wave the reflected sound wave and the normal at the point of incidence all lie in the same plane .
• the angle of reflection of sound is always equal to the angle of incidence of the sound .

____________________

b) the speed of sound increases on a Ho today when the temperature is high and it require a larger distance from the reflecting surface from the Echo to be heard . Since the distance between the reflecting surface and the source of sound remain the same no Echo can be heard on a hotter day .

c) the two practical application of reflection of sound waves are ;

• the reflection of sound wave is utilised in the working of megaphone .
• the reflection of sound wave is utilised in the working of a stethoscope .
