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 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.
How does the angle of the refraction compare with the angle of incidence in each case?
A comparison of the angle of refraction to the angle of incidence provides a good measure of the refractive ability of any given boundary. For any given angle of incidence, the angle of refraction is dependent upon the speeds of light in each of the two materials. The speed is in turn dependent upon the optical density and the index of refraction values of the two materials. There is a mathematical equation relating the angles that the light rays make with the normal to the indices (plural for index) of refraction of the two materials on each side of the boundary. This mathematical equation is known as Snell's Law
What is image transformations?
They are 4 different images plotted on the Cartesian plane and they are:- Translation moves each point of a shape in the same distance and direction Reflection a mirror image of a shape Enlargement changes size of a shape by a given scale factor Rotation turns a shape at a given angle and at a fixed point

How do find internal angle of polygon if number of side is given?
360/n
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.
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 parallel light rays reflect off each mirror below looks like with a ruler
Explain how you can find the measure of an angle complementary to a given angle an angle supplementary to a given angle?
1 plus 2 is equal to 3
How many degrees are in a supplementary angle?
A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
What angle do you use when giving an intravenous injection?
GENERALLY, THE INJECTION IS GIVEN AT 450 angle....... but also depends upon the site of an administration. Subcutaneous are given at 150-180 angle and, intramuscular can be given at an angle of 450 or, 900.
