1. Photon energy is proportional to frequency. If one doubles, so does the other.
2. If you are talking about light transmission, frequency and period do not depend upon humidity. Speed and wavelength do, but only slightly
im talking about sound waves
1. Sound power depends upon pressure amplitude and speed, not frequency. What do you mean by a "pulse" of sound? If it is a short burst, energy will also depend upon how long the pulse is.
The speed and wavelength of sound depend very weakly upon humidity. They mainly depend upon temperature and average molecular weight. Frequency and period are independent of humidity.
