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 do you compare the angle of incidence and the angle refraction?

The angle of incidence is the angle between the incident ray and the normal to the surface, while the angle of refraction is the angle between the refracted ray and the normal to the surface. These angles are related by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media the light is traveling through.


Why is it necessary for the angle of refraction to be equal to the angle of incidence when the angle of incidence is zero?

When the angle of incidence is zero, it indicates that the incident ray is perpendicular to the surface. In this case, the angle of refraction needs to be zero as well in order to maintain the direction of the light without any deviation. This ensures that the light continues to travel in a straight line as it passes through the interface between the two mediums.


When angle of incidence is equal to angle of refraction?

When the angle of incidence is equal to the angle of refraction, it means that the light is traveling from one medium to another with the same refractive index. This condition is known as the critical angle, and beyond this point, total internal reflection occurs.


Why angle between the incident ray and the normal is called angle of incident?

The angle between the incident ray and the normal is called the angle of incidence because it represents the angle at which the light ray strikes the surface. It is important in understanding how light behaves when it interacts with a surface, such as reflection or refraction.


Why is the angle of refraction zero in newton's ring exp?

The angle of refraction is zero in Newton's ring experiment because the incident light is perpendicular to the plane of the glass plate, so refraction does not occur. This allows for constructive interference between the incident and reflected light waves, leading to the formation of interference rings.

The law of reflection states that the angle of incidence is equal to the angle of refraction?

The law of reflection states that the angle of incidence is equal to the angle of REFLECTION. Refraction is an entirely different phenomenon and has its own law.


What are the terms related to refraction of light?

terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation


Does the index of refraction equal the angle of refraction?

Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index


What are the laws of refraction of light?

laws of refraction are as follows:=1) the incident ray, refracte dray and the normal at the point of incidence all lie on the same plane.==2) the sine of the angle of incidence to the sine of angle of refraction is a constant.this is also called the snell's law.=

When light is incident on a surface at 30 degrees it is found that reflected ray and refracted ray are perpendicular to each other Find angle of refraction How?

When light is incident on a surface at 30 degrees and the reflected and refracted rays are perpendicular, it means the angles of reflection and refraction add up to 90 degrees (since they are complementary angles). Therefore, the angle of refraction can be calculated as 60 degrees by subtracting the incident angle from 90 degrees. This is based on the principle of Snell's Law, which states that the angle of incidence and angle of refraction are related through the refractive indices of the two mediums.
