One astronomer is studying the nature of an electromagnetic wave emitted by hot gases in the universe. the electromagnetic wave has higher frequency than visible light but lower frequency than gamma rays. what electromagnetic wave is the astronomer most likely studying?

x-ray

radio wave

microwave

infrared light

X - rays

Explanation:

One astronomer is studying the nature of an electromagnetic wave emitted by hot gases in the universe.

We know that frequency is defined as the number of oscillations or vibrations per unit time.

We have to write name of the electromagnetic wave whose frequency is higher than visible light but lower than gamma rays.

Frequency of visible light is

Frequency of gamma rays is more than

The frequency of X-rays lies between visible light and gamma rays i.e. the frequency of X - rays is in between  

Hence, the correct option is (A) " X - rays ".
