What is the frequency of a wave

The frequency of a wave, represented by the letter f, is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The SI unit of cycles per second is called hertz or Hz. Hz can be expressed as a reciprocal second (s-1 or 1/s).

The number of waves that pass a point in 1 second

What is the energy of a photon

the energy of a photon is h times f

How are frequency speed and wavelength related

they are related by the equation velocity=frequency*wavelength

Which of the following colors of visible light has the highest frequency
