Why do we look further away in convex mirrors then in a normal mirror?
because you see more area than in a plane mirror.
What is the plane mirror explain formation of images by a plane mirror?
the image in a plane mirror is always
What is plan mirror?
A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.
Is the reflecting surface of a sculpture a plane surface like that of a plane mirror?
No. It is not a plane surface like that of a plane mirror because a plane mirror is straight and it does not have any curve in it. the sculpture's surface is like that of a Convex Mirror
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 type of mirror is a dental mirror?
It's just a normal mirror scientifically known as a "plane mirror".

What is the angle between a plane mirror and the straight line joining the object and its image?
90 degrees (That line is the normal to the mirror.)
What angle is the same distance from the normal on a plane mirror as the incident angle?
The angle of reflection.

Definition of plane mirror?
A plane mirror is a mirror which is completely flat, easier for your image to be reflected.

What types of mirror are used in periscope?
plane mirror
Light strikes a mirror at 20 degrees to the normal what will the angle of reflection be?
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 a light ray is shone at a mirror?
It is reflected. Depending on the shape of the mirror, this can be at a variety of angles. Assuming the question refers to a flat mirror that is hung on a wall; a plane (flat) mirror has an imaginary straight line at a right-angle to it, called the normal. A ray of light hits the mirror at an angle to the normal, but is reflected at the same angle that it hits the mirror in the opposite direction. So if a ray hits the mirror at 45 degrees from the normal, it will be reflected at 45 degrees from the normal in the opposite direction.
