  3. Can we apply this equation to a sound wave?

What kind of sound wave does a piano make?

Sound waves are mechanical waves, and in a piano the majority of the mechanical waves produced are transverse, other than the occasional longitudinal wave produced by tension in the string. Longitudinal waves in a piano are caused from the local increase in tension caused by the wire's elongation.

How can sound waves be described mathematically?

The frequency of a sound can be calculated by dividing the rate of the compressions and rarefactions by the length of a soundwave. An oscilloscope is an electronic device that is often used to measure and visualize a sound's frequency.

Can we apply this equation to a sound wave?

Solution : Yes. It is a universal relationship and applies to all waves.
