Question

relation between wavelength , frequency and velocity

Answer 1

hello dear friend ⭐⭐⭐⭐⭐⭐

________________

your answer ⭐⭐⭐

What is the relation between frequency, wavelength and velocity?

here it is,,,,,,

v=f⋅λv=f⋅λ

So velocity is directly proportional to wavelength and frequency.

For electromagnetic waves it's

c=f⋅λc=f⋅λ

Look up the wavelength and frequency of a certain part of the spectrum and test this out. They'll always approximately produce the speed of light.

So, at least for electromagnetic waves, the ratio between frequency and wavelength must remain constant while in a vacuum.

We know that frequency is directly proportional to the energy level of an electromagnetic wave

E=hfE=hf

E=hcλE=hcλ

We also know that photons do not lose energy when moving through different mediums.

So we must conclude that frequency remains constant while wavelength changes to compensate for its new velocity within the medium.

I hope it will help you ✨✨✨✨

Answer 2

hi
That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation that relates wavelength and frequency forelectromagnetic waves is: λν=c whereλ is the wavelength, ν is the frequency and c is the speed of light.
