The main difference between mechanical and electromagnetic waves is as follows: mechanical waves need a substance such as a liquid to travel through. Electromagnetic waves, on the other hand, do not need any substance or medium to travel through. Electromagnetic waves are transmitted in a vacuum while mechanical waves are not transmitted in a vacuum. As mentioned above, mechanical waves travel in a substance or medium such as water. An example of mechanical waves is when a stone is thrown into the water. The resulting ripples are mechanical waves. Examples of electromagnetic waves are light waves or radio signals.

Einstein primarily emigrated to the United States because he had a Jewish background, and Adolf Hitler, who became Germany's chancellor in 1932, was about to adopt Anti-Semitic policies.
It was a very hard choice for Einstein to choose to emigrate to the United States, but it was a very wise one. As a Jew, he knew what was gonna happen if he stayed in the United States. You may already know that the Holocaust happened a few years later, in which most Jews living in countries occupied by Germany were murdered. Thanks to moving to the U.S, Einstein was safe from this event.
