Question

If frequency is kept constant, how are the velocity and wavelength of a wave related?

A.
They are directly proportional to each other.
B.
They are inversely proportional to each other.
C.
They are not related.
D.
They are equal to each other.

Answer 1

`velovity = frequency * {lamda}`

Therefore : velovity is directly proportional to wave length (lamda)

The answer is A

Answer 2

They are directly proportional to each other.

Explanation:

Given : If frequency is kept constant,

To find : how are the velocity and wavelength of a wave related.

Solution : We have given

frequency is kept constant,

We know the relation between velocity frequency and wavelength.

Velocity = frequency * wavelength .

Now we kept the frequency constant.

Then ,

Velocity ∝ wavelength.

∝ represent the directly proportional sign and frequency is constant o proportionality.

Therefore, They are directly proportional to each other.
