What the critical angle and is and what happens to light and the ceitical angle?

It spells "critical" correctly


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


Is the critical angle the same thing as the angle of incidence?

The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.


How do you find critical angle of an object?

The critical angle is the angle where the wave is refracted at 90 degrees. Using Snell's law, nisinxi=nrsinxr, the two indexes of refraction, and the definition of a critical angle, it's pretty easy to figure out. Keep in mind that the critical angle ONLY occurs when the wave is travelling from a denser medium to a less dense medium (eg diamond to air) as angles formed when travelling into less dense mediums turn away from the normal, whereas if the opposite were to occur, even with an angle of incidence of 90 degrees, the angle of refraction would be less than 90 (it would turn towards the normal). The denser the medium, the larger its index of refraction value. knowing this, the equation would look something like: (larger n)sin(critical angle)=(smaller n)sin(90 degrees) Where you would input the known values and solve for the critical angle. Another tip is that sin(90 degrees) is just 1 so you could even just ignore that variable.

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.


What must be the critical angle if total internal reflection occured in diamond?

The critical angle for total internal reflection in diamond is approximately 24.4 degrees. This means that any light ray entering diamond at an angle greater than 24.4 degrees will be reflected back inside the diamond, rather than refracted out.


What is critical reflection?

The smallness of the critical angle Θc for diamond means that light is easily "trapped" within a diamond and eventually emerges from the many cut faces. This makes a diamond more brilliant than stones with smaller n and larger Θc. Traveling inside a diamond, a light ray is incident on the interface between diamond and air.


What is the definition of critical angle?

The definition of critical angle is the angle of incidence that refraction can still occur.

Why critical angle for water is greater than the critical angle of glass?

Because of the difference in the density of the materials.


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.


Will you get a more total internal reflection with a medium that has a small critical angle or with OR that has a large critical angle?

You will get more total internal reflection with a medium that has a smaller critical angle. A smaller critical angle means that light is more likely to be reflected back into the medium rather than refracted out of it.
