A laboratory had the folowing apparatus available in it :
(A) Two thin hollow wooden tubes
(B) An intense and board source of sound
( C) An intense pointed source of sound
(D) A sharp pointed detector to detect the sound
( E) A well polished metal sheet
(F) A white painted thermocol sheet
A student can do his experiment to verify the laws of reflection of sound successfully by choosing the appartus labelled as :

A

A, C, D, E

B

A, C, E

C

A, B, D, E

D

A, C and D

Text Solution

Verified by Experts

The correct Answer is:
A
An intense pointed source and a sharp pointed detector should be perferred. For guiding the path of sound as incident and reflected sound waves, wooden tubes are required. A polished metal sheet acts as a good reflecter of sound.
