Question

Velocity of light in vacuum 3× 10^8 m/s and that in water 2.3 ×10^8 m/s, if the wavelength of of a wave in vacuum is 6× 10^-7 m. What is the wavelength in water?explain its urgent​

Answer 1

Answer:

Nothing can travel faster than the speed of light."

"Light always travels at the same speed."

Have you heard these statements before? They are often quoted as results of Einstein's theory of relativity. Unfortunately, these statements are somewhat misleading. Let's add a few words to them to clarify. "Nothing can travel faster than the speed of light in a vacuum." "Light in a vacuum always travels at the same speed." Those additional three words in a vacuum are very important. A vacuum is a region with no matter in it. So a vacuum would not contain any dust particles (unlike a vacuum cleaner, which is generally full of dust particles).
