Question

You want to create a new warming appliance that is safe. Which type of electromagnetic wave would be most useful to investigate?

- X-rays
-infrared waves
-gamma rays
-ultraviolet waves

Answer 1

Infrared waves. The other 3 would hurt you because they are below the UV scale of 400 nanometers. Infrared is light that wouldn't harm you

Answer 2

-infrared waves

Step-by-step explanation:

If electromagnetic waves are arranged in order of their energy in lowest to highest order then it is as following

1) Radio waves

2) Microwaves

3) Infrared waves

4) Visible light

5) Ultraviolet waves

6) X Rays

7) Gamma Rays

So here if we wish to use to create a safe device for warming which would be of lesser and safe energy

so here correct answer would be

Infrared waves
