Glass
In naturally occurring media the slowest speed occurs in diamond at well under half c. Look up its refractive index, it is the highest.
the speed of light, commonly denoted as "c", is constant no matter which medium it passes through.
Light does not change speed when it goes through glass.
Diffraction.
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
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.
the speed of light, commonly denoted as "c", is constant no matter which medium it passes through.
Zero (0) light cannot pass through opaque materials.
Light does not change speed when it goes through glass.
When the speed of light in the two media is not the same.
it travels at c (speed of light in a vacuum)
speed of light will decreases
Diffraction.
Its speed and wavelength change.
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
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.
The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.
