It gets refracted. That means that a light ray leaves the surface at an angle, going down closer to the vertical. Coming up it's refracted away from the vertical.
The theory is based on James Clerk Maxwell's electromagnetic theory , one of main theories of classical physics. Maxwell combined electricity and magnetism into one unified theory by demonstrating that light travels in the form of a plane wave made up from electric and magnetic fields. It was a theory that followed on from earlier experiments by Ampere and Faraday.
Maxwell wrote down formulas describing the behaviour of both these fields, and then added a notional extra term into one of the equations to make them look more balanced. He was a professor of mathematics and did it as a mathematical exercise. From that he did a few steps of algebra with his new equations to show that light travels as a plane wave, and its speed depends on a property of the material called the dielectric constant.
It was 10-15 years before people believed this theory but when Heinrich Hertz discovered radio waves and showed that they also travel as plane waves, there was little more doubt and the whole new technology of radio communications, radar and broadcasting took off.
What else can I help you with?
What happens to a speed of a light ray as it passes from water to air?
It gets faster. As a result, it also changes its direction.
What happens when light is refracted through water from air?
When light passes from air into water, it undergoes refraction, causing it to change direction. This is due to the change in speed of light as it moves from a less dense medium (air) to a denser medium (water). The light ray bends towards the normal (an imaginary line perpendicular to the surface) when entering the water.
When light passes from water into air the light bends away from the normal true or false?
False. When light passes from water into air, it bends towards the normal.
What is a example of light refacting?
A rainbow happens when sunlight is refracted by drops of water in the air.
What happens to frequency when a ray of light passes from air to water?
The frequency of light remains constant when passing from air to water. However, the speed of light changes due to the change in the medium, causing the wavelength to change. This change in wavelength results in the light bending or refracting at the interface between air and water.
What happens when light passes air into water?
it slows down.
What happens to the speed of light as passes from water to air?
It increases.
What happens to light as it passes from air into water in one word?
slowdown
What happens to a speed of a light ray as it passes from water to air?
It gets faster. As a result, it also changes its direction.
What happens to the velocity and wavelength of light when it passes from air into water?
The speed of the light decreases, and its wavelength increases by the same factor.
What happens when light is refracted through water from air?
When light passes from air into water, it undergoes refraction, causing it to change direction. This is due to the change in speed of light as it moves from a less dense medium (air) to a denser medium (water). The light ray bends towards the normal (an imaginary line perpendicular to the surface) when entering the water.
When light passes from water into air the light bends away from the normal true or false?
False. When light passes from water into air, it bends towards the normal.
What happens to the speed of the light when it passes from air into glass?
The speed decreases.

The frequency of light remains constant when passing from air to water. However, the speed of light changes due to the change in the medium, causing the wavelength to change. This change in wavelength results in the light bending or refracting at the interface between air and water.
This happens when light bends as it passes throw water?
Refraction occurs when light changes direction as it passes from one medium to another, such as from air to water. This bending of light is due to the change in speed of light as it enters a denser or less dense medium, causing the light rays to change direction.
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.
