How do you compare the angle of incidence and the angle refraction?
The angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
The relationship between the angle of incidence and the angle of refraction is known as law?
Snell's Law states that the ratio of the sines of the angles of incidence and refraction is equal.
Why is the ratio of angle of incidence to the angle of refraction is equal to constant?
Snell's law stipulates that the ratio of the sines as regards the angles of incidence in addition to that of refraction is a constant influenced by the media.
What are the snells law of refraction?
Snell's law states that the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of velocities in the two media, or equivalent to the opposite ratio of the indices of refraction:
How do you calculate the angle of refraction?
The angle of refraction can be calculated using Snell's Law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the velocities of light in the two media. The formula is given as sin(theta1) / sin(theta2) = v1/v2, where theta1 and theta2 are the angles of incidence and refraction, and v1 and v2 are the velocities of light in the two media.

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.
Describe an experiment to find the refractive index of a glass block?
You can investigate fraction in glass using a rectangular glass block. By tracing the rays of light on a piece of paper, you can measure the angles of incidence (i) and refraction (r). If you repeat this process for a range of different angles of incidence, you would find that the sine of the angle of incidence and the sine of the angle of refraction are constant. This ratio is called the refractive index of the material, and is given the letter n.The angles of incidence and refraction are related by the following equation:sin in=__________sin r

What happens when a light ray travels at right angles into a transparent object?
When light travels at right angles into a transparent object (i.e. angle of incidence is zero), no refraction occurs.
What is the reference line in measuring the angles of incidence and angle reflection?
The reference line is the normal (perpendicular) to the surface.
What are two angles formed by the beam of light as it bends its way into and out of the prism?
The angle of incidence and the angle of refraction, both measured relative to a normal to the surface
Why does the incident angle not equal the angle of refraction?
i=incidence angle, r=angle of refraction Refractive index= sini/sinr Since for different materials value of refractive index is different hence both angles are not equal.
How does the angle of incidence compare with the angle of refraction 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
