Explanation:

Here some of the pairs of terms are given. We need to find the incorrect relation. The relation are as follows :

1. amplitude of a sound: intensity of the sound

2. frequency of sound waves: number of wavelengths

3. quality of a sound: frequency of the sound

4. frequency of sound waves: loudness of the sound

The intensity of sound is directly proportional to the square of its amplitude. So, relation 1 is correct.

If f is the frequency and [tex]\lambda[/tex] is the wavelength. Speed of sound wave is,

[tex]v=f\lambda[/tex]

So, relation 2 is correct.

The quality of sound wave depends on its amplitude. So, relation 3 is not correct.

The vibration depends on two factors i.e amplitude and the frequency. The loudness of sound depends on the amplitude of wave. So, relation 4 is incorrect.
