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.
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.

What is the critical angle of perspex and water?
The Critical angle of perspex is 42o.It is the same as the critical angle of glass.
What is the definition of critical angle?
The definition of critical angle is the angle of incidence that refraction can still occur.
Why is a small critical angle desirable for optical fibers What problems could be caused if the critical we're increased?
because a smaller critical angle means that it is easier for total internal reflection to occur, which is the desirable quality in an optical fibre.

Define critical angle?
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
When do you have critical angle?

Is critical angle fixed?
Yes for a given medium critical angle is fixed as mu = 1/ sin C mu is the refractive index of the material and C is the critical angle.
Why critical angle for water is greater than the critical angle of glass?
Because of the difference in the density of the materials.

How do you draw the critical angle?
hand
Explain what the measure of an angle is?
the measure of an angle is the degrees of an angle.
