What did Albert Einstein have to do with radiation?

Answer 1

He was only indirectly related to it. He created the premise and formula E=MC2. (energy = mass times the speed of light squared). This was the formula for splitting the atom, and following that the atom bomb was developed in the USA, and two were dropped on Hiroshima and Nagasaki in Japan after they bombed Pearl Harbor and brought the US into WWII. The two bombs ended the war. However, radiation resulted from the detonation of the bombs, and citizens close enough to the impact, or also a few miles away, were adversely affected by the radiation.

Answer 2

Albert Einstein's work in the early 20th century contributed to our understanding of the photoelectric effect, which is the emission of electrons from a material when exposed to light. This work helped to support the idea that light can behave as both a wave and a particle, laying the foundation for the field of quantum mechanics. His contributions to the theory of relativity also influenced how we understand the behavior of light and radiation in the universe.
