When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
What will happen to a light ray incident on a glass-to-air boumdary at greater than the critical angle?
Anything greater than critical angle will cause the light to just be reflected.
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
What the critical angle and is and what happens to light and the ceitical angle?
It spells "critical" correctly
Could you Explain the critical angle?
hi the critical angle is when the light comes in and it reflects
What Critical angle of light passing from glass to water is minimum from?
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.
Is there a critical angle for light traveling from glass to water?
Yes, there is a critical angle for light traveling from glass to water. This critical angle is the angle of incidence that results in light being refracted along the interface between the two mediums, rather than being transmitted into the other medium. The critical angle can be calculated using Snell's Law.

As a ray of light passes from air into glass the angle it makes with the surface normal will?
Decrease if the light is entering the glass at an angle greater than the critical angle, and increase if the light is entering the glass at an angle less than the critical angle. The angle the ray makes with the surface normal is known as the angle of refraction.
What is the critical angle for glass to air surface?
The critical angle for glass to air surface is approximately 42 degrees. This means that when light travels from glass to air and the angle of incidence exceeds 42 degrees, total internal reflection occurs.
What will happen to a light ray incident on a glass-to-air boumdary at greater than the critical angle?
Anything greater than critical angle will cause the light to just be reflected.
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
What will happen to a light Ray incident on a glass-to-air boundary at greater than the critical angles?
If a light ray is incident on a glass-to-air boundary at an angle greater than the critical angle, total internal reflection will occur. This means that all of the light will be reflected back into the glass medium and none will be transmitted into the air.
What best describes why the critical angle of an air-glass boundary is 39.3?
The critical angle of 39.3 degrees occurs at the air-glass boundary due to the change in optical density between air and glass. Beyond the critical angle, light is totally internally reflected rather than refracted, resulting in a condition where no light passes through the boundary.
Which color of light passing from glass to air has minimum critical angle?
The color of light that has the minimum critical angle when passing from glass to air is red. This is because red light has the longest wavelength of all the visible colors, which leads to a smaller change in speed and a larger angle of refraction at the interface between the two mediums.
What is the critical angle of perspex and water?
The critical angle for perspex and water is approximately 41 degrees. This means that any light ray entering perspex from water at an angle greater than 41 degrees will be totally internally reflected within the perspex.
What is the critical angel for total internal reflection in most glass?
The critical angle for total internal reflection in glass is approximately 42 degrees. This means that any light ray entering the glass at an angle greater than 42 degrees will be reflected back into the glass rather than refracted out of it.
