Question

The following electromagnetic radiation is harmful to us

1. Radio waves
2. visible light
3. microwave
4. Ultraviolet radiation

Answer 1

Given the options: Infrared, Radio waves, Ultraviolet and Visible light, ordering them by frequency (for highest to lowest) we get:

Ultraviolet

Visible light

Infrared

Radio waves

Knowing that high-frequency radiations are likely to cause harm to astronauts landing on Mars, then the detector of Ultraviolet is most suitable

Step-by-step explanation:

Answer 2

4. ultraviolet radiation

Step-by-step explanation:

because I think uv is more far apart(high wavelength) from the rest so that its energy is higher and it can damage more.
