A sound wave travels at a speed of 340m/s. If its wavelength is 2cm, what is the frequency of the wave in Hz? Will it be in the audible range?

What are the differences between softer sound and louder sound?

In which of the following cases softer sound will be produced?

The softness of sound depends on the amplitude of the soundwave.

Softness of a sound can be determined by _____.

Which wave property determines pitch?

Name the characteristic which helps us distinguish between a man's voice and a woman's voice, even without seeing them.

Which property cannot be transferred by a wave?
