Question

if light travels from vaccum to water ,its wavelength is​

Answer 1

Answer:

For a light in vacuum, its frequency changes when wave length changes. ... So when light travels through glass or water the velocity decreases as that are optically denser and the wavelength gonna decrease.λ = μλ

For water, μ>1So, λ

<λ

Answer 2

Answer: It's wavelength will decrease as light travel fastest in vacuum then in gas , slower in liquid and slowest is solid . Speed of light in vacuum is 3x100000000 m/s or 3 x 10 to the power 8 and the speed of light in water is approximately 2.26×10 to the power 8 meters per second.

So, the wavelength will decrease.
