The energy of the light having a frequency of 2. 30 × 10¹⁷ Hz is 15.2398 x 10⁻¹⁷ J

The frequency of the light = 2.3 x 10¹² Hz

The energy of the photon can be found using the formula

          E = hν

where E is the energy of the photon

           h is the Planck constant (6.626 x 10⁻³⁴ Js)

           ν is the frequency of the light

So, let us substitute the known values in the above equation, we get

               E = 6.626 x 10⁻³⁴ x 2.30 x 10¹⁷

                  = 15.2398 x 10⁻³⁴ x 10¹⁷

                  = 15.2398 x 10⁻¹⁷ J


Therefore, the energy of the light is 15.2398 x 10⁻¹⁷ J
