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.
Could you Explain the critical angle?
hi the critical angle is when the light comes in and it reflects
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.
When the angle of incidence is greater than the critical angle all light within the material is?
hte light is reflected
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 when it strikes the boundary of the two media an angle equal to the critical angle?
It gets refracted so that its direction of propagation is the boundary line.
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.
The refractive index of diamond is 2.42. What is the critical angle for the light passing from the diamond to the air?
The critical angle is the angle of incidence at which the light is refracted at an angle of 90 degrees. The critical angle can be calculated using Snell's Law: sin(critical angle) = 1 / refractive index. For diamond (n=2.42) to air (n=1), the critical angle is approximately 24.4 degrees.
How does total internal reflection depend on the angle of incidence of light rays?
Total internal reflection occurs when the angle of incidence is greater than the critical angle. The critical angle is the angle at which the refracted ray would be at 90 degrees to the normal. If the angle of incidence is less than the critical angle, the light ray will be refracted out of the material.
What is meant by the critical angle?
A 'critical angle', is bascially the smallest angle of incidence for which light can be totally reflected. Incidence is the arrival of a particle or beam of light at a surface. I.e. If a beam of light hits a desktop at the angle of 45 degrees, the angle of incidence will be 45 degrees.
What happens if a ray's angle of incidence exceeds the critical angle?
If a ray's angle of incidence exceeds the critical angle when travelling from a denser medium to a less dense medium, total internal reflection occurs. This means that the light is entirely reflected back into the denser medium, rather than being refracted.
What are the conditions of total internal reflection?
Total internal reflection occurs when a light ray traveling from a denser medium to a less dense medium strikes the interface at an angle greater than the critical angle. The critical angle is the angle at which the light ray is refracted along the interface. If the angle of incidence is greater than the critical angle, all of the light is reflected back into the denser medium.
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 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.
Why total internal reflection takes place?
Total internal reflection occurs when light travels from a medium with a higher refractive index to one with a lower refractive index, at an angle greater than the critical angle. This phenomenon happens because at angles beyond the critical angle, the light is completely reflected back into the denser medium, rather than refracted out into the less dense medium.
