Question

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

Answer 1

$velovity = frequency \times {lamda}$

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

The answer is A

Answer 2

Answer:

They are directly proportional to each other.

Step-by-step 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.
