Question

The energy of a photon is proportional to its a) amplitude. d) wave number, k-2m/A c) velocity. b) frequency

Answer 1

Frequency

Step-by-step explanation:

Photons are the packet of energy. They are massless and chargeless particles. They travel in the vacuum with the speed of light. The energy of photon is given by :

`E=h\\u`

Where

h = Planck's constant

`\\u` = frequency of photon

Or
`E=(hc)/(\lambda)`

c = speed of light

`\lambda` = wavelength of photon

From the above equation, it is clear that the energy of photon is directly proportional to its frequency.
