Velocity (speed and direction) Wavelength (frequency)
It means that the wave changes direction when it passes from one medium to another - for example, from air to water, or from denser air to less dense air.
It slows and bends.
When light passes into the slab it is changing medium from less to more dense. When that happens the light slows down and bends towards from the normal
Light bends when it passes at an angle into a medium of a different density. When light passes from a less dense medium into a denser medium, like from space into Earth's atmosphere or from air into water, it bends toward the normal, which is an imaginary line perpendicular to the boundary between the two media where the light passes through. Light passing from a denser medium to a less dense medium bends away from the normal.
The light bends when it passes from one medium to another. But only if it approaches the interface at an angle. In such a case it will still travel slower, but there will be no apparent bending.

The answer depends on what on earth you mean by the "dirtier" of a wave.

The only way light can speed up is if it passes from a more-optically-dense medium to a less-optically-dense one, like from glass into air, or from air into vacuum. When that happens, if the light doesn't hit the boundary in the direction that's perpendicular to it, then the light will change direction. That's how lenses work.
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE
