What else can I help you with?
The of a substance is the speed of light in a vacuum divided by the speed of light in that substance?
refractive index
How is the index of refraction of a substance related to the speed of light in the substance?
The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.
What happens when light passes into a denser substance?
When light passes into a denser substance, it undergoes refraction - its direction changes because the speed of light is slower in the denser substance. The light ray bends towards the normal (an imaginary line perpendicular to the surface) at the point of entry into the denser substance.
How is the index of refraction of s medium related to the speed of light inThe medium?
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
How can light refract?
Light hits a substance. The substance makes light change speed. Light gets scattered through the substance. Then the light bends.
What happens when a light ray moves from one substance to another?
When a light ray moves from one substance to another, it can undergo refraction, reflection, or absorption. Refraction occurs when the light ray changes speed and direction as it enters a new medium. Reflection happens when the light ray bounces off the surface between the two substances. Absorption occurs when the light ray is absorbed by the new medium.
What happens to the speed of light in motor oil?
As long as the light remains in the motor oil, nothing happens to its speed.
How can light be refracted?
Light can be refracted when it passes from one medium to another with a different density, causing its speed to change. The change in speed leads to a change in the light's direction, causing it to bend. This bending is what we observe as refraction.
How is the refractive index of one medium with respect to the otherrelated to the speed of light?
The refractive index of any substance is(speed of light in vacuum)/(speed of light in that substance) .The number is greater than ' 1 ' in any material medium.
What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
What is the velocity of car light?
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
What happens to light when it passess from one substance to another?
Light can be absorbed, transmitted, or reflected when passing from one substance to another. The change in speed and direction of light as it enters a new medium can cause phenomena such as refraction or total internal reflection, depending on the optical properties of the materials involved.
