What equation shows how velocity is related to frequency and wavelength?

Propagation velocity of a wave is propotional to the product the wave's frequency (f) and wavelength (lambda):

The correct answer is .

Explanation:

The expression of the wavelength in terms of the frequency is as follows;

Here, c is the speed of the light, f is the frequency of the wave and is the wavelength of the wave.

The wavelength and the frequency has an inverse relationship between them.

If the frequency of the wave increases then the wavelength of the wave decreases.

If the frequency of the wave decreases then the wavelength of the wave increases.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is 75.0%.
