Question

2. Ultraviolet radiation has a frequency of 6.8 x 10'5Hz. Calculate the energy, in
joules, of the photon.

Answer 1

Answer:

$E=4.5\times 10^{-18}\ J$

Explanation:

It is given that, the frequency of Ultraviolet radiation is $6.8\times 10^{15}\ Hz$

We need to find the energy of the photon. The formula for the energy of a photon is given by :

$E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63\times 10^{-34}\times 6.8\times 10^{15}\\\\E=4.5\times 10^{-18}\ J$

So, the energy of the photon is $4.5\times 10^{-18}\ J$.
