Question

This is Science not Math

Certain high-frequency radiations are likely to cause harm to astronauts landing on Mars. A detector for which type of electromagnetic radiation is most suitable to study this harmful radiation on Mars?

Infrared

Radio waves

Ultraviolet

Visible light

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

Explanation:

Answer 2

Answer: Third option is correct.

Explanation:

Certain high-frequency radiations are likely to cause harm to astronauts landing on Mars.

Ultraviolet is the most suitable to study this harmful radiation on Mars.

It has highest frequency than X-rays but shorter than visible rays.

It is harmful is nature as it causes painful sunburns and premature ageing of the skin etc.

Hence, Third option is correct.
