How can one determine the critical angle for a given material interface?
To determine the critical angle for a given material interface, you can use Snell's Law, which relates the angles of incidence and refraction at the interface. The critical angle occurs when the angle of refraction is 90 degrees, causing the light to be refracted along the interface. By calculating the critical angle using Snell's Law, you can find the angle at which total internal reflection will occur.
What will the angle of reflection when the angle between the incident ray and the reflecting surface of the mirror is 30 degree?
You have given the glancing angle as 30 degree. So the angle of incidence = 90-30 = 60 deg As i = r by the law of reflection the angle of reflection = 60 deg
What must be the critical angle if total internal reflection occured in diamond?
The critical angle is given by the formula: Thetac = sin-1(n2/n1) Assuming a diamond-air boundary, this gives the critical angle as: Thetac = sin-1(1.00/2.42) = 24.4 degrees.
What describes when light bounces off a surface?
When light bounces off a surface, it undergoes reflection. The angle of incidence (angle at which light strikes the surface) is equal to the angle of reflection (angle at which light bounces off the surface). The Law of Reflection governs this interaction between light and surfaces.
What has the minimum critical angle- red or violet?
The critical angle is lower for violet light than for red light. This means that violet light is more prone to total internal reflection at an interface between two different materials at a given angle of incidence compared to red light.

How do find internal angle of polygon if number of side is given?
360/n
How do you measure the complement and supplement of an angle in trigonometry?
Complement of a given angle = (90 - given angle) Supplement of a given angle = (180 - given angle)
What is the angle or refraction when the angle of incidence is 40degrees?
That depends on the substances where the refraction occurs. The relationship between the angles, and the index of refraction of both materials, is given by Snell's Law.
What is the angle of refraction when the angle of incidence is equal to the critical angle?
Quick Answer:The angle of incidence is not equal to the angle of refraction.The angle of incidence is equal to the angle of reflection.Better Answer:(This answer applies to all waves, e.g. sound, ripples, earthquakes, but the answer is given in terms of light waves.)The angle of incidence never equals the angle of refraction except in the peculiar circumstance when there is an interface between two materials of exactly the same index of refraction.The angle of refraction is the direction of the wave exiting the surface and the angle of incidence is the angle entering the surface.These two angles are related by Snell's law and by Snell's law one would conclude that the index of the medium of the incident beam would be exactly the same as the index of the transmitted beam. In optical terms, it would mean the wave propagates as though there were no interface and the two mediums were actually the same medium. In that case, there would be no reflection as well.So, one does not expect this to happen, not because it can't, but because the wave travels through the surface as though the surface did not exist and that is both unusual and uninteresting.
What name is given to a clear reflection?
A clear reflection is called a mirror image.
