The reflection angle will also be 20 degrees from the normal on the other side of the normal in the same plane.

What happens when normal incidence strikes mirror?

When light with normal incidence strikes a mirror, it reflects back at the same angle in the opposite direction. This is known as specular reflection, where the angle of incidence is equal to the angle of reflection.


What are the values of angle of incidence and angle of reflection for normal incidence of light on a plane mirror?

put a real answer on here, not Study and youll "Know" not now


What is the angle between the normal and the surface of a mirror?

The angle between the normal and the surface of anything is by definition always 90 degrees, regardless of whether it is a mirror, a piece of concrete, a wooden plank, etc.


What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?

If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.


What happened when light strikes at the mirror?

it reflects of the mirror. a very small part of light is absorbed by the mirror a rest of it is reflected back in the same medium . following the 1st law of reflection , a ray of light falling on a mirror is reflected back making an equal with the "Imaginery normal to the point of incidence."


What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?

The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.


A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surfaceWhat will be the angle of reflection?

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 ^


Light beam hitting the mirror at 75 degrees what angle would it reflect?

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.


What is the angle of reflection of a light ray that hits a mirror at a 48-degree angle from the normal line?

96 degress? If the light ray is straight, and if the mirror isn't bent, then the angle of reflection is exactly 48 degrees, the same number of degrees as the angle of incidence. That's the law of reflection.


What are value of angle of incidence and angle of reflection for normal incidence of light on mirror?

The angle of incidence is 0 degrees for normal incidence, meaning the light ray hits the mirror perpendicularly. The angle of reflection is also 0 degrees, as the reflected ray will be in the same direction as the incident ray.


When describing image formation in mirrors what is the angle of reflection?

The angle of reflection is the angle between the reflected ray and the normal to the mirror surface. According to the law of reflection, this angle is equal to the angle of incidence, which is the angle between the incident ray and the normal.


What is the angle of incidence of a reflected wave bounces off a mirror at an angle of 65 degrees?

The angle of incidence is equal to the angle of reflection when a wave bounces off a mirror. If the wave reflects at an angle of 65 degrees to the normal (the line perpendicular to the surface at the point of reflection), then the angle of incidence is also 65 degrees. Thus, both the angle of incidence and the angle of reflection are 65 degrees.
