Question

How does energy relate to wavelength and frequency?

Answer 1

Energy increases as the wavength decreases and the frequency increases.

Explanation:

Long wavelength, low frequency waves, such as radio wave seas are thought to be harmless. They don’t carry much energy and are therefore considered safe by most people.

As the wavelength decreases and frequency increases, the energy increases - for example X-rays and gamma radiation. We know those are harmful to humans.

Answer 2

Please see below.

Explanation:

This relates to energy of a photon. We know the relationship between wavelength (represented by `lambda`) and frequency (represented by `nu`), according to to which they are inversely related and their product is the velocity of wave and in case of photon it is represented by `c`.

The relation in case of photon is given by

`E=(hc)/lambda` or `E=hnu`, where `h` is Planck's constant i.e, energy is directly proportional to frequency and inversely proportional to wavelength.
