Question

What precautions should be taken while performing the experiment to verify the law of reflection of sound?

Answer 1

Precautions that should be taken while performing the experiment to verify the law of reflection of sound

1. The angle of reflection of sound waves should be determined carefully, till the sound heard is the loudest.
2. No direct sound waves from the source should reach the listener.
3. For an accurate recording of the angle of incidence/ reflection of sound using the pipes, the centre most part of the pipe should match the line of incident sound wave and hence the same for the reflected sound wave.
4. The reflecting surface should be smooth.
