Why frequency is more fundamental than wavelength?

  • #1
Please any one explain that why frequency is more fundamental than wavelength inspire wavelength and frequency depend upon each other again frequency and wave number are also depends upon each other
Then why we take the frequency as independent of wave number

I haven't noticed writing that treats one as more fundamental than the other, but I can see why one might wish to think of it that way.

Frequency does not change as the medium through which the wave is travelling changes, but wavelength does. As light goes from vacuum to air to glass, its speed changes, and its wavelength changes accordingly, but the frequency remains the same.

To the source, the frequency seems more fundamental... (as andrewkirk says, the wavelength of the resulting disturbance depends on its propagation speed in the surrounding medium).

1. You may want to consider the use of punctuation.

2. This requires CONTEXT. As has been stated, while frequency doesn't change when light goes from one medium to another, this DOES NOT make frequency "more fundamental".

3. Why does this matter?
