The speed changes. (and sometimes the angle.)
that changes the speed of the light, which makes the light bend
The direction of light propagation can be changed at the boundary of two media having different densities. This property is called refraction, and is illustrated in the following figure for the boundary between air and water.
Conduction-happens when heat moves from one object to another through direct contact Radiation-happens when energy ,such as heat, moves in waves between one object and another Convection-happens when matter carries heat from one place to another
In a vacuum, light travels at a constat speed. It won't get faster or slower over time. In other substances (e.g., in water) light moves at a speed determined by the characteristics of the substance. Here, it won't get slower or faster with time, either.
When an electron absorbs a single photon of light it moves from its current shell to an outer shell.
The refraction of light means that although light travels in straight lines, when it moves from one substance into another, it can change direction. This happens because the wave changes speed as it travels between different types of materials.As a light wave travelsbetween diffrent clear substances, the light wave bends. When light passes one substance to another, the light changes direction.
The ray of light bends towards the normal.

It moves at a slower speed!
Thermal energy that can move from one substance to another is called heat. Heat always moves from a warmer substance to a cooler one. An increase in temperature means that heat moves into a substance.
The speed increases.
