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 else can I help you with?
Is the angle of incidence the same as angle of refraction?
No, the angle of incidence is the angle between the incident ray and the normal line, while the angle of refraction is the angle between the refracted ray and the normal line. In general, these angles are not the same, except in the case of normal incidence where they are both zero.
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.
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 happens to a ray of light when it travels from a more dense medium into a less dense medium?
It will be refracted accordingly, based on Snell's law. In this case, the angle of incidence is smaller than the angle of refraction, and as it is traveling from a more dense to a less dense medium, it may undergo total internal reflection, provided that the angle of incidence is greater than the critical angle.
What are characteristics of refraction?
1. When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...
How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?
Angle of refraction will be less compared to the angle of incidence in this case.

What happens to the angle of incidence from air to glass?
The angle of incidence does not change. I think you want to know the relationship between the angle of incidence and the angle of transmission. In the case of from air to glas, the transmission angle is smaller than the angle of incidence due to a higher index of refraction of glass than that of air. Look up Snell's Law for better understanding.

Which numbered angle represents the angle of the incidence?
The angle of incidence is typically labeled as the angle formed by the incoming ray of light and the normal to the surface. In the case of a diagram with numbered angles, it is usually denoted as the angle labeled "i."
Why the ray of light does not bend when it passes perpendicularly from rarer medium to denser medium?
When light passes perpendicularly from a rarer medium to a denser medium, there is no change in the speed of light. Since refraction occurs due to the change in speed, the absence of speed change in this case results in no bending of the light ray.
When a ray of light enters water from air then?
Light will undergo refraction, and the light rays will bend towards the normal, because it is entering an optically denser medium. In this case, the angle of refraction will be smaller than the angle of incidence. In addition, the speed of light will be reduced when travelling in water.
What is the angle of incidence if the angle of reflection is 15 degrees?
If the ray is incident at right angles to the reflection surface, angle of Incidence will be 90 degrees and so will be the angle of reflection. In such a case, the incident ray, the normal and the reflected ray coincide.
