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 index of refraction of air is considerably less than the index of refraction
for water. This is an indication that when light transitions the boundary out
of water and into air, its speed increases..
The speed of light itself actually increases, based on what recent studies say. If this question truly does mean from water to air, and not the other way around, then this is true. While the speed (very slightly) increases, the ray of light will attempt to "straighten itself out" to face upwards, an initial position for light passing from water to air, or vise-versa.

What happens to the speed of light when it travels from air into water?
The speed of light decreases when it travels from air into water because light travels slower in denser mediums. This change in speed is due to the different refractive indices of air and water, which affects the velocity of light propagation.
What happens to the velocity and wavelength of light when it passes from air into water?
When light passes from air into water, its velocity decreases due to the higher refractive index of water. This results in the light's wavelength also decreasing.
What happens to the speed of electromagnetic waves when they go from air to water?
The speed of electromagnetic waves decreases when they transition from air to water because water has a higher refractive index than air. This causes the waves to bend or refract as they enter the water.
How you calculate the speed of light in water?
Assuming the speed of light in air is already known (it is close to the speed of light in a vacuum), you might check how the light refracts when it changes from air to water (at what angle), and then use Snell's Law.
How does the speed of light change when it enters the water?
The speed of light decreases when it enters water due to the higher refractive index of water compared to air. The decrease in speed is a result of the light wave interacting with the water molecules, causing it to slow down.
What happens to the speed of light as it moves from water into air?
The speed increases.
What happens to the speed of light as passes from water to air?
It increases.
What happens to a speed of a light ray as it passes from water to air?
The speed of light increases as it passes from water to air. This is due to the difference in the refractive indexes of water and air, causing the light to travel faster in air compared to water.
What happens to the frequency of light as it goes from air to water?
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.
What happens when light goes from water to air?
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.
What happens to the speed of light when air changes to gas?
I'm afraid nothing happens to the speed of light ever. Also "air" is consider'd a gas.
What happens to the speed of the light when it passes from air into glass?
The speed decreases.
What happens to the speed of light when it travels from air into water?
The speed of light decreases when it travels from air into water because light travels slower in denser mediums. This change in speed is due to the different refractive indices of air and water, which affects the velocity of light propagation.
What happens when light bends and travels through water?
When light enters water, it slows down due to the increased density of water compared to air. This change in speed causes the light to bend or change its direction, a phenomenon known as refraction. The amount of bending depends on the angle at which the light enters the water.
Is this true or false that light moves slower through water than through air?
Yes it is true. If c is the speed of light in air then in water it will be 3/4 of c Hence refractive index of water = speed of light in air/speed of light in water So refractive index = 4/3 = 1.333
What happens to the velocity and wavelength of light when it passes from air into water?
When light passes from air into water, its velocity decreases due to the higher refractive index of water. This results in the light's wavelength also decreasing.
What happens to the speed of electromagnetic waves when they go from air to water?
The speed of electromagnetic waves decreases when they transition from air to water because water has a higher refractive index than air. This causes the waves to bend or refract as they enter the water.
