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

Ultraviolet

Explanation:

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

sure im new too!

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
