What is the mathematical support for the formula $f_n = n f_1$, used to calculate the frequency of a standing wave? [closed]
could someone explain to me the mathematical support for the formula $f_n = n f_1$. This formula refers to the fact that the frequency of a standing wave is equal to the number of antinodes times the ...

Doppler effect for multiple sources [closed]
Given the figure below, how can I determine the speed from the two sources given that they both produce a frequency of 1000 Hz, and the speed of sound can be assumed to 340 m/s. The sources are both ...

Relationship between frequency of light and photocurrent in photoelectric effect
As we know, the frequency of incident light is postulated to have no effect on the photocurrent. But coming to think, about both quantities should be related. Consider the formulae
$$I=\frac{q}{t} \\ ...

Pound-Rebka Experiment
Does anyone know if the velocity of the photons changes in the Pound-Rebka experiment?
Do the wavelength and the frequency change simultaneously, so that there is no change in the velocity, or do they ...

How to picture vibrational overtones of water?
Im trying to understand the colour of water. The absorption occurs because of some of the vibrational overtones of water.
The absorption band at 698 nm (14300 cm−1) is a 3rd overtone (n=4)
The ...
