If I combine 2 laser beams of different wavelengths, would I get a beat frequency of the difference between the 2 lasers? Thanks, Bill

It could be a misunderstanding, but a coworker who is 13 years younger than myself remembers being taught the same thing. Thank you for the clarification.

In Elementary School, many years ago, we where taught Earths gravity is created because our planet rotates. And if the rotation stopped, we would have no gravity. My present understanding is gravity comes from an objects mass. It seems rotation would be a result of gravity, not the creator of...
