Question

Determine the energy of a photon whose frequency is 1.59x10^17 Hz.

Answer 1

Answer:

The answer is

$1.05 \times {10}^{ - 16} \: \: \: J$

Explanation:

To find the energy of the photon we use the formula

E = hf

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 1.59x10^17 Hz

We have

$E = 1.59 \times {10}^{15} \times 6.626 \times {10}^{ - 34}$

We have the final answer as

$1.05 \times {10}^{ - 16} \: \: \: J$

Hope this helps you
