Question

What is the importance of Microwaves in radio astronomy

Answer 1

Answer

• These waves are high in frequency hence low in wavelengths and carry higher energy than visible light.
• They can reach larger distances, penetrate opaque interstellar substances compared to visible light.
• Since they can travel much longer distances, there is a possibility they come from faraway objects which helps scientists to investigate the birth and death of those objects, distance to them and as well known facts like the age of the universe etc.
• Since they are electromagnetic waves their possibility to be treated very similar to visible light has been another plus point.
