This is due to the difference in optical density.
Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
The light will bend as it passes through.
Because glass slab is optically denser than air.
light rays bend away from normal as it passes from denser water to rarer air

It is because the glass has more refractive index than air which makes the light bend more through glass than air.

The speed of light slows in water.
The speed decreases.
no
Refraction. White light is a mix of colors in the first place; these colors have different indices of refraction. That is, when moving from air to glass, as in a prism, they will bend at slightly different angles.

Change in speed of the light in glass. Fermat showed that time is invariant in light paths. This results in Light following the Law of Signs. sin(Air Angle)/speed in air = sin( Glass Angle)/speed in glass .
