Calculate the total energy in 1.5 x10^13 photons of gamma radiation having lambda = 3.0*10^-12

The total energy of the given photons in the radiation is 0.994 J.

The given parameters;

The energy of  a single photon is calculated as follows;

E = hf

where;

The energy of a photon in the radiation is calculated as;

The total energy of the given photons is calculated as follows;

Thus, the total energy of the given photons in the radiation is 0.994 J.

0.99 Joules

Explanation:

The relationship between wavelength and frequency of the wave follows the equation:

where,

= energy of the wave

N = number of photons =

h = plank constant =

c = speed of light =

= wavelength of the wave =

Putting all the values:

The total energy in photons of gamma radiation having lambda = is 0.99 Joules
