Question

What is the difference between power and frequency?
For example, if you increase the power of a light (40W to 80W), the energy of the photons do not change because the frequency has not changed. Can someone explain how this works??

Answer 1

Take note on the definitions:
Power is the rate of energy dispersion.
Frequency is the rate of movements per unit time.
Apparently, both can be similar, in such way that the power involves only energy, whereas frequency does not.
Increasing the power of light means increasing the energy dispersed per unit time, which is the light energy or thermal energy.
Unlike the frequency, which determines that the rate at which the photons pass through a given point is the same as the design of the apparatus did not change.
