Describe how the speed of sound was affected by changes in amplitude and frequency in the lab experiment.

experiment the speed of sound does not depend on the amplitude and is proportional to the frequency,

Explanation:

The speed of sound is given by the expression

       v = √ B /ρ

Where B is the module of Bulk and ρ is the density of the material

We see that this speed does not depend on the amplitude, therefore it does not change in the laboratory experiment.

The amplitude is related to the sound intensity heard

The speed of the wave is also given by the equation

        v = λ f

This expression is valid for any type of wave. We can see that in this case the speed is directly proportional to the frequency,

The frequency is related to sound higher treble for higher frequencies and bass for low frequencies.

Therefore in summary in a given experiment the speed of sound does not depend on the amplitude and is proportional to the frequency

it doesn't. it was imagined up in the middle ages.
