Complete Question:
Which of the following electromagnetic waves carries the highest energy, and are most damaging to human?
A. Gamma Rays
B. Microwave
C. Radio-wave
D. Alpha Rays
Correct Option:
Gamma Rays carries the highest energy, and are most damaging to human.
Option: A
Explanation:
The waves of light and other forms of energy that radiate or travel from where they are originated is understood as electromagnetic radiation, and collectively represent electromagnetic spectrum. The gamma rays are dangerous sources of radiation with high energy. Its standard size is 0.000001 nm i.e. size of atomic nucleus diameter. It results from the degradation of atomic nuclei by radioactive means. It is made up of the smallest electromagnetic wavelength, and thus provides the highest photon energy.
