Calculate the energy of a photon of wavelength 11.56 meters. (planck’s constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108 m/s)

Answer : The energy of a photon is,

Explanation :

Formula used :

where,

E = energy = ?

h = Planck's constant =

c = speed of light =

= wavelength = 11.56 m

Now put all the given values in the above formula, we get the energy.

Therefore, the energy of a photon is,
