A reflected ray in a mirror makes an angle of 20 and deg with the incident ray. when the mirror is rotated 15 and deg what angle will the reflected ray now make with the incident ray?
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.
Why does a ray falling normally on a plane mirror retrace its path?
When a ray falls normally on a plane mirror, it is reflected back along the same path due to the law of reflection, which states that the angle of incidence is equal to the angle of reflection. Since the incident angle is zero degrees, the reflected ray also follows the same path.
What happens when a ray of light is directed at a mirror?
When a ray of light is directed at a mirror, it will reflect off the mirror's surface at an equal angle but in the opposite direction. This is known as the law of reflection. The angle of incidence, which is the angle between the incident ray and the normal to the mirror's surface, will be equal to the angle of reflection, which is the angle between the reflected ray and the normal.
What is the reflected ray when it is reflecting on another mirror?
When a ray of light reflects off a mirror and then onto another mirror, the direction of the reflected ray is determined by the angle of incidence relative to the surface of the second mirror. The law of reflection states that the angle of incidence equals the angle of reflection, so the reflected ray will bounce off the second mirror at an equal but opposite angle to the incident ray.
An activity to show that the incident ray the reflected ray and the normal at the point of icident ray lie in the same plane?
Place a plane mirror on the table. Take a paper sheet and make a small hole in its centre. Make sure that the light in the room is not bright. Hold the sheet normal to the table. Take another sheet and place it on the table in contact with the vertical mirror. Draw a normal line on the second sheet from the mirror. Now, light a torch on the mirror through the small hole such that the ray of light falls on the normal at the bottom of the mirror. When the ray from this hole is incident on the mirror, it gets reflected in a certain direction. You can easily observe the incident ray, reflected ray and the normal to the mirror at the point of incidence on the sheet placed on the table. This shows that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
A light ray hitting a mirror at an angle is reflected off at angle?
The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.

What is a line of reflection?
A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equall the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

It is 0 degrees.

A light wave was reflected off of a mirror at an angle of 10 degrees What was the incident angle?
The incident angle to the Mirror will be 10 deG.
What are the light rays called that leave a mirror?
The light rays that leave a mirror are called reflected rays. They are the result of light bouncing off the mirror's surface at an equal angle to the incident angle.
How many reflected rays can there be for a single incident ray falling on a plane mirror?
Substitute "photon" for "ray" and it's one. One photon falling on a plane mirror will come back off of the reflective surface if that reflective surface does not absorb it. (In a perfect plane mirror, every photon that falls on the surface will be reflected.) A photon does not "create" a second photon in a reflection event.
What is the light ray which shines away from a mirror?
The reflected light ray that shines away from a mirror is called the "incident ray." It represents the path taken by light as it approaches and then reflects off the mirror surface.
