It slows from c to c/n where n is the refractive index of water
Its speed and wavelength change.
speed of light will decreases
The speed of light though substances is slower than the speed of light in a vacuum. As the light passes from air to water it slows and the ray's path is translated towards the normal to the air/water interface slightly.
It gets faster. As a result, it also changes its direction.
a denser medium hav more no.of particles also > the no.of particles > the opposition provided for..... therefore both wavelength and speed of light changes but frequency remains the same.
it travels at c (speed of light in a vacuum)
Its speed and wavelength change.
the speed of light, commonly denoted as "c", is constant no matter which medium it passes through.
They'll leave your car at the speed of light, and when that light passes anybody, they'll measure the speed of the light as it passes them to be the speed of light.
It moves at a slower speed!
The speed decreases.
It increases.
That depends what it comes out of. If it passes into air from vacuum, thenits speed decreases. If it passes into air from water or jello, then its speedincreases.
When the speed of light in the two media is not the same.
Diffraction.
speed of light will decreases
Zero (0) light cannot pass through opaque materials.
