Question

How many types of mirrors are there? Name them, define them.

Answer 1

There are mainly three types of mirrors: - Plane mirror, Concave Mirror, Convex Mirror. Plane Mirror is that this mirror has a plane surface. This type of mirror is utilized in our homes. The concave mirror has the spherical mirror's inner surface reflecting. The convex mirror is that the spherical mirror's external surface is reflecting.

Complete step-by-step solution:
The mirror creates a virtual image of whatever is in the reverse angle from the viewer, meaning that the body in the image appears to be in a direct line of vision—behind the mirror's surface—at an identical distance from their location in front of the mirror. Objects following the observer, or between the observer and the mirror, are reflected by the observer without any real change in adjustment; the light waves are inverted in a direction perpendicular to the mirror.
There are different types of mirror: -
A mirror is a horizontal piece of glass coated with an element alloy in its most primary form, which permits the glass to reflect a clear image—this is called a plane mirror. Plane mirrors are the most common type found in bedrooms, bathrooms, and department building dressing rooms. A plane mirror gives images near-identical in appearance and size to objects located in front of it.
A convex mirror projects outward and represents a slightly deformed image more minor than the actual. It does this by showing at a wider angle near the ends than at the centre. Convex mirrors are helpful for security purposes since they permit us to recognize more than a plane mirror—passenger-side mirrors in cars are a typical example. Crafty marketers have also supposed that using curved mirrors in clothing store dressing rooms can increase sales by presenting shoppers to appear longer and leaner.
A concave mirror, identified as a converging mirror, curves the interior like a spoon. Concave mirrors reflect light inside to a single focal point; this is why they focus light. From far away, images reflected in a concave mirror appear upside down, but the picture flips and becomes amplified as we get closer. Dentists utilize concave mirrors to increase the size of teeth, in shaving and makeup mirrors, in car headlights, and to ignite the Olympic torch.

Note: When a light ray comes on the reflecting surface, it gets reflected back. Light is energy, and energy can both be reflected or absorbed. Here, mirrors display light energy. Mirrors are reflective and not the other smooth white surface because the mirror is flat at a microscopic level. When the light energy knocks the rough surface, the light bounces back in all directions, identified as diffuse reflection. However, for a smooth surface, the bouncing back of light appears in one direction and is known as specular reflection.
