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.
What is the ray of light traveling parallel to the principal axis of a concave mirror that will be reflected out through the mirror?
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected through the focal point of the mirror after reflection.
What is the line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins called?
The line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins is called the normal line.
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.
What will happen when a ray of light is shone at a mirror?
When a ray of light is shone at a mirror, it will be reflected following the law of reflection, where the angle of incidence is equal to the angle of reflection. The reflection will produce a mirror image of the object or light source.
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 the difference between an incident ray and a reflected ray?
The ray which hits or falls on a object or a material initially is known as INCIDENT RAY. The ray which gets reflected after hitting the object is known as REFLECTED RAY.

Can a ultraviolet ray be reflected bby a mirror?
yes
What is the line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins called?
The line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins is called the normal line.
Where are the angles of the incident ray and reflected ray measured from?
The normal to the reflecting surface.
What will happen when a light is shone at a mirror?
it will reflect off it

What is the angle of incidence if a reflected wave bounces off a mirror with an angle of reflection equal to 55º?
If a light ray is reflected from a flat mirror with a reflection angle of 55o then the angle of incidence was also 55o. When reflecting from a mirrored surface, the angle of incidence equals the angle of reflection.
What will happen when a ray of light is shone at a mirror?
When a ray of light is shone at a mirror, it will be reflected following the law of reflection, where the angle of incidence is equal to the angle of reflection. The reflection will produce a mirror image of the object or light source.
What is a ray that bounces off the mirror?
A ray that bounces off a mirror is called a reflected ray. When light hits a mirror, it reflects off at the same angle it approached the mirror, following the law of reflection.
