Answer 1

Answer:

when light reflects any object

Answer 2

Dear Mate !

Explanation:

1.A) When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light.

2.A)

(a) An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface.

(b) When a line is drawn perpendicular to the reflecting surface at the point of incidence, this line is known as normal.

(c) Lateral inversion - The phenomenon of left side appearing right side and right side appearing left side on reflection in a plane mirror is called lateral inversion.

(d) Question is inappropriate.

3.A) Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.

4.A) Silvering is the common term given to the chemical process by which the reflective medium, (or 'mirror') is created. It is aluminium oxide, not silver that is cooled and stuck onto a sheet of glass, in a vacuum, thus coating the back surface to get the desired mirror effect.

5.A) The process of bending of light while travelling from one medium to another is called refraction. And glass slabs and other transparent object having higher density than air or comparing object are called refracting mirror.

6.A) Plane mirrors produce images that have a magnification of 1. In conclusion, plane mirrors produce images with a number of distinguishable characteristics.

7.A) A plane mirror may be considered to be a part of an infinitely large spherical surface.

And, an infinitely large spherical surface will have infinite radius.

So, radius of curvature for a plane mirror will be infinite.

8.A)

Following are the types of mirrors that are most widely used:

Plane mirror:

The images formed from a plane mirror are the reflected images in their normal proportions but reversed from left to right. These are the most widely used mirrors.

Convex mirror:

These are the spherical mirror that is curved outward and the image obtained is virtual, diminished and erect for a real object.

Concave mirror:

These are the spherical mirror that is curved inward and the image obtained from these mirrors depend on the placement of the object.
