Question

Represent graphically by two separate diagrams in each case.

Two sound waves having different amplitudes and also different wavelengths indicate :

• A. same frequencies
• B. different frequencies
• C. one same and one different
• D. None of these

Answer 1

The correct option is B different frequencies

Below is the diagrammatic representation of Two sound waves having different amplitudes and also different wavelengths. In both the wave forms the crests and troughs are at different heights indicating different amplitudes, and the number of crests and troughs per unit of time are different indicating different frequencies.
