Question

the most energetic electromagnetic radiation originates from:
(a) Nuclear reactor
(b) Outer space
(c) Nucleus of H atom
(d) Ultrasonic rocket​

Answer 1

I think it's outer space ..

Answer 2

Electromagnetic radiation with most energy originates from Outer space

Explanation:

• Option b is the answer - Outer space

• Most energetic electromagnetic radiation is gamma rays which has shorter wavelength and higher frequecy.

• The Gamma rays naturally originate from decay of radioactive element and interaction of radiation from outer space with cosmic particles.

• Artificial source of it is fission which take place in nuclear reactor . Gamma rays are ionising that can excite the electron of cause that is why it can affect to human health as it can lead to mutation in genes.

• Increasing order of energy - radio waves < microwaves < infrared < visible  light < ultraviolet < X-rays < gamma ray
