SPM Physics Revision 5.3 Reflection of Waves 5.3.2 Reflection of Sound Wave

Reflection of Sound Wave

Experiment

Conclusion:

  1. The angle of incidence, i is equal to the angle of reflection, r.
  2. Sound waves obey the law of reflection. That is, the angle of incidence is equal to the angle of reflection.

Q & A

Why hard plywood is used?

A hard surface is a good sound reflector. Hard plywood is used so that only very little energy is lost during the reflection.

Q & A

Why mechanical stopwatch is used as a source of the sound?

Because its sound is not loud enough to be heard directly by the observer.

Q & A

Why cardboard tube is used?

The cardboard tube is used to help to direct the incident and reflected sound waves.

Q & A

Why softwood is used?

The softwood can absorb any sound from the stopwatch and prevent it from reaching the observer.
