Question

What is the smallest packet of electromagnetic energy that can be absorbed or emitted?

Answer 1

Photons is the smallest packet of electromagnetic energy that can be absorbed or emitted.

Step-by-step explanation:

Photons

The energy packets of the electromagnetic radiation that can be either absorbed or emitted.these are particles which transmit light into space.

There energy of the photon is given by Planck's equation:

`E=h\\u =(h* c)/(\lambda)`

where,

E = energy of photon = ?

h = Planck's constant =
`6.63* 10^(-34)Js`

c = speed of light =
`3* 10^8m/s`

`\\u` = frequency of the photon

`\lambda` = wavelength light emitted by photon
