What is the frequency of an electromagnetic wave with energy of 5.0 x 10-20
j?

7.546 × 10^13 Hz

Explanation:Electromagnetic waves are types of waves that do not require a material medium for transmission.They include x-rays, radio waves, visible light, and microwaves among others.Electromagnetic waves travels at the speed of light and possess energy.Energy of electromagnetic waves is calculated by the formula, E = hf, where h is the plank's constant and f is the frequency of the wave.

In this case;

Energy, E = 5.0 × 10^-20 Joules

We are required to find the frequency, f

Using the equation;

E = hf

f = E ÷ h

 = 5.0 × 10^-20 J ÷ 6.626 × 10^-34 J-s

= 7.546 × 10^13 Hz

= 7.55 × 10^13 Hz

Thus, the frequency of the electromagnetic wave is 7.55 × 10^13 Hz
