when light passes from water to glass it's wavelength
Answers
Answer:
Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, too. The wavelength decreases as the light enters the medium and the light wave changes direction.
Explanation:
Answer:
Its wavelength decreases.
Explanation:
We know that the frequency of the wave remains constant when the wave is traveling from one medium to another.
It is also known relation that:
Velocity of the wave = frequency x wavelength
From here, we know that velocity of wave changes and frequency doesn't. Hence the wavelength should change for the equation to be true. It is this change that causes refraction of light.
As the wave is traveling from a rarer medium to a denser medium.
Velocity of the light decreases, frequency remains same and hence wavelength decreases
Hope this helps ☺.
