One astronomer is using an electromagnetic wave to study the structure of the milky way galaxy. the electromagnetic wave has more energy than radio waves but less energy than visible light. what electromagnetic wave is the astronomer using?

x-ray

gamma ray

microwave

ultraviolet radiation

Microwave  

Explanation:

It is given that the electromagnetic wave has more energy than radio waves but less energy than visible light.

The energy of an electromagnetic wave depends on its frequency. Greater the frequency, greater would be the energy of the waves.

The EM wave which has greater energy than radio waves but less than visible rays is Microwaves and Infrared. Ultraviolet radiation and X-ray has greater energy than visible light.

Thus, from the given options, correct answer is Microwave.

god i hope this !
