Answer:
Photons is the smallest packet of electromagnetic energy that can be absorbed or emitted.
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:
[tex]E=h\nu =\frac{h\times c}{\lambda}[/tex]
where,
E = energy of photon = ?
h = Planck's constant = [tex]6.63\times 10^{-34}Js[/tex]
c = speed of light = [tex]3\times 10^8m/s[/tex]
[tex]\nu [/tex] = frequency of the photon
[tex]\lambda[/tex] = wavelength light emitted by photon
