I Need Help ASAP! 50 POINTS!!!

Answer 1

Answer:

The answer is

$3.313 \times {10}^{ - 19} \: \: \: J$

Explanation:

The energy of a photon can be found by using the formula

E = hv

where

E is the energy

v is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

v = 5.0 × 10¹⁴ Hz

So the energy is

$E = 5.0 \times {10}^{14} \times 6.626 \times {10}^{ - 34}$

We have the final answer as

$3.313 \times {10}^{ - 19} \: \: \: J$

Hope this helps you
