When a light ray passes from air into water at an angle of 30 degrees from the normal, it undergoes refraction. The angle of refraction can be calculated using Snell's Law, which states n1sin(theta1) = n2sin(theta2), where n1 and n2 are the refractive indices of air and water, respectively, and theta1 and theta2 are the angles of incidence and refraction. Given that the refractive index of air is approximately 1 and water is approximately 1.33, the angle of refraction can be calculated to be approximately 22.6 degrees using Snell's Law.
15 degrees from the normal - on the other side.
When a light beam hits a mirror, it reflects at an angle equal to the angle of incidence, according to the law of reflection. If the light beam hits the mirror at 75 degrees relative to the normal (the line perpendicular to the surface), it will reflect at an angle of 75 degrees on the opposite side of the normal. Thus, the angle of reflection is also 75 degrees.
The angle of incidence would be 90 degrees, so the angle of refraction is 0 degrees, as the light ray does not deviate.
It is reflected at exactly the same angle, but on the other side of the normal at the point of incidence.
By convention angles are measured from the normal to the reflecting surface. The angle of incidence, 35 degrees, is equal to the angle of reflection. In this case 35 degrees. The answer is 35 degrees.
15 degrees from the normal - on the other side.
The reflection angle will also be 20 degrees from the normal on the other side of the normal in the same plane.
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.

Perpendicular light rays do not refract when entering a new medium because they do not change their direction when passing through the boundary between the two mediums. This is because the angle of incidence is 0 degrees, making the angle of refraction 0 degrees as well. Since the light ray continues along the normal line, there is no bending of the light ray.
The angle of reflection is equal to the angle of incidence. It will be at 30o to the surface of the mirror (from the opposite edge) ^ This answer is not correct for SURFACE, but is correct for RELATIVE ^
The angle of refraction for a beam of light striking a diamond at an angle of 45 degrees will depend on the refractive index of the diamond material. The angle of refraction would be less than 45 degrees due to the bending of light as it enters the denser medium of the diamond.
If light rays entered from one medium to another at 90 Degrees of the surface between the mediums, then the light rays would not be retracted. The light will straight through from the first medium to the second.
When light enters or exits water into air at an angle of 15 degrees with the normal, the light ray will refract, or bend, away from the normal. This is because water is optically denser than air, causing the light to bend towards the less dense medium.
It is reflected at exactly the same angle, but on the other side of the normal at the point of incidence.
By convention angles are measured from the normal to the reflecting surface. The angle of incidence, 35 degrees, is equal to the angle of reflection. In this case 35 degrees. The answer is 35 degrees.
