That depends what it comes out of. If it passes into air from vacuum, then
its speed decreases. If it passes into air from water or jello, then its speed
increases.
The speed of light depends on the electrical properties of whatever substance it's in. It has nothing to do with what substance it used to be in before, or what substance it's going into next. -- If it goes from air into vacuum, its speed increases. -- If it goes from air into water, its speed decreases. -- If it goes from water into air, its speed increases. -- If it goes from water into diamond or jello, its speed decreases.
the speed of light never changes but when the light beam goes from air to water, it refracts. this is when the light beam alters direction because it hits an object of greater or less density (in this case it is higher).
The speed of light decreases when it travels from air into glass because the glass has a higher refractive index than air. This causes the light to slow down as it moves through the denser medium.
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
It speeds up. Air and water are both media (plural form of medium). Each one of them has a different speed of light. As the incident ray passes from air to water, it refracts to be closer to the normal. A refraction occurs when there is a change in the speed of light. A change in the speed of light occurs when there is a change in media. In this case the media is changed from air to water. The second medium (water) must also have a lower speed of light in order for refraction to occur
The frequency of light remains constant as it changes medium from air to water. However, the speed and wavelength of light will change, causing it to bend or refract.
I'm afraid nothing happens to the speed of light ever. Also "air" is consider'd a gas.
The speed decreases.
The speed increases.
When light goes from water to air, it undergoes refraction, causing it to change speed and direction. This change in speed and direction is due to the different optical densities of water and air. As a result, the light ray bends away from the normal line at the water-air boundary.
Light changes speed and direction when it goes from air into glass. This phenomenon is known as refraction. The change in speed causes the light to bend, which is why objects may appear distorted when viewed through a glass surface.
It increases.

If the speed of light were the same in air and water, then the pencil would appearstraight, NOT broken. The beginning of the simplest explanation of why it doesappear broken is the fact that the speed of light is different in air and in water,and that causes light to bend when goes from one into the other.
When light passes from air to glass, it undergoes refraction, which is the bending of the light ray due to the change in speed as it moves from one medium to another. The speed of light is slower in glass compared to air, causing the light ray to bend towards the normal.
