Problem

What is the correct order of decreasing energy?

1. microwaves, visible light, x-rays, γ-rays. ultraviolet light

2. visible light, microwaves, x-rays, γ-rays, ultraviolet light

3. visible light, ultraviolet light, microwaves, x-rays, γ-rays

4. microwaves, visible light, ultraviolet light, x-rays, γ-rays

5. γ-rays, x-rays, ultraviolet light, visible light, microwaves

Solution

We’re being asked to rank the given electromagnetic radiation in order of decreasing energy


We’re given the following radiation:

Visible Light        Ultraviolet Light        Microwaves               X-Rays                 γ-Rays


Recall that in the electromagnetic spectrum, radiation:

• On the left side: has high energy and frequency and a low wavelength

• On the right side: has low energy and frequency and high wavelength
