Amplitude

There's an inverse relationship between frequency and wavelength. Do they have any relationship with the amplitude of a wave?

Re: Amplitude

I believe amplitude is independent of both regarding EM since the speed is fixed.

Re: Amplitude

Amplitude is a measure of length or distance similar to wavelength, but has no relation to frequency! I think it’s just a quantity that can be measured or solved for

Re: Amplitude

Wavelength and frequency are inversely related, as when they are multiplied, they result in a constant. I believe that amplitude is a separate value with no relation to the other two. For example, a wave might have a set frequency, and thus a set wavelength to compensate. The amplitude could be any value and the wavelength and frequency would still be able to remain the same.

Re: Amplitude

No, amplitude is a measure of the height of a wave and is related to how much energy that wave has. This is unrelated to frequency and wavelength which have an inverse relationship in regards to the speed of a wave.

Re: Amplitude

If you want a more physical approach to the relationship between amplitude to that of frequency and wavelength, then I suggest attempting 1A. 3. It is on page 9 and after solving it, I understand the concepts much more.
