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

Is refraction angle equal to the angle of reflection?
No.
Does the angle of incidence always equal the angle of refraction?
Usually not.
The angle of reflection is equal to the .......?
The angle of incidence
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.
How do you work out angle of refraction with refractive index?
You can use Snell's Law. Note that you need two angles for this - the incoming angle, and the outgoing angle.
Why does the incident angle not equal the angle of refraction?
The incident angle does not always equal the angle of refraction because of a phenomenon called refraction. Refraction occurs when light passes through a boundary between two different mediums, causing the light to change speed and bend. This bending of the light ray results in the incident angle and angle of refraction being different unless the light is entering the medium perpendicular to its surface.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
How does the angle of refraction change as the index of refraction of the bottom material increases?
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.
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.
What happens to light as it moves at an angle into a medium that has a lower index of refraction?
Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.
How does increasing a mediums index of refraction affect the angle of refraction?
Increasing the medium's index of refraction causes the angle of refraction to decrease when light passes from a medium with a lower index of refraction to a medium with a higher index of refraction. This is due to the relationship described by Snell's Law, which governs the change in direction of a light ray as it passes from one medium to another.
How does the index of refraction affect the critical angle?
The critical angle is determined by the relationship between the indices of refraction of two media. When light travels from a medium with a higher index of refraction to one with a lower index, the critical angle decreases. Conversely, if light travels from a lower index to a higher one, the critical angle increases.
How can the index of refraction for different substances be determined mathematically?
The index of refraction of a substance can be determined mathematically using Snell's Law, which relates the angle of incidence and refraction to the refractive indices of the two substances involved. By measuring the angles of incidence and refraction, the index of refraction can be calculated using the formula n = sin(i) / sin(r), where n is the refractive index, i is the angle of incidence, and r is the angle of refraction.
Is refraction angle equal to the angle of reflection?
No.
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 can you calculate the index of refraction of a material based on the critical angle?
You can calculate the index of refraction of a material based on the critical angle using Snell's Law. The equation is n = 1 / sin(critical angle), where n is the index of refraction of the material. The critical angle is the angle at which light is refracted along the boundary between two materials, typically from a more optically dense material to a less dense one.
What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees?
The minimum index of refraction for total internal reflection at a 45-degree angle is 1.41. This means that the glass or plastic prism would need to have an index of refraction greater than or equal to 1.41 to achieve total internal reflection at that angle.
