Answer

Uses Of Spherical Mirror

-it is generally know as shaving mirror coz it's makes an enlarged and erect image of the user

- Used in car headlights and in the street lights as light reflector

- Also used in vehicle as side mirror

Answer

There are two types of spherical mirror
1.concave mirror and 2.convex mirror
uses of concave mirror
1.automobile headlights
2.torch lights
3.reflecting telescope
4.solar furnance

uses of convex mirror
1.vehicle mirror
2.magnifying glass
3.correction of hypermetropia
4.microscope

Answer

The first mirrors used by humans were most likely pools of water. The earliest known manufactured mirrors were polished stone pieces.

Back in 500 AD, Chinese people began making mirrors with silver-mercury amalgams.

Claudius Ptolemy conducted various experiments with curved polished iron mirrors.

Terminologies

There are a few basic terminologies that one needs to know while studying spherical mirrors, and they are:

Center of Curvature

The point in the centre of the mirror that passes through the curve of the mirror and has the same tangent and curvature at that point.

Radius of Curvature

It’s the linear distance between Pole and the Center of curvature.

Principal axis

The imaginary line passing through the optical center and the center of curvature of any lens or a spherical mirror.

Pole

The midpoint of the spherical mirror.

Aperture

An aperture of a mirror or lens is a point from which the reflection of light actually happens. It also gives the size of the mirror.

Principal Focus

Principal Focus can also be called Focal Point. It’s on the axis of a mirror or lens wherein rays of light parallel to the axis converge or appear to converge after reflection or refraction.

Focus

It’s any given point, where light rays parallel to the principal axis, will converge after getting reflected from the mirror.

Spherical mirrors are of two types and they are classified as follows:

Concave Mirror

Convex Mirror

Answer

Introduction:
Spherical mirrors are mirrors whose reflecting surface is shaped like a part of a sphere. They are widely used in various applications due to their ability to form different types of images. The uses of spherical mirrors can be categorized based on the type of image formed, which can be either real or virtual.

Uses of Spherical Mirrors Based on Images Formed:

1. Formation of Real Images:
Real images are formed when the reflected rays actually converge and can be obtained on a screen. Spherical mirrors are used in the following applications to form real images:

- Telescopes: Spherical mirrors are used in reflecting telescopes to gather and focus light from distant celestial objects. The concave mirror in a reflecting telescope forms a real image at the focal point, which is then magnified by an eyepiece.

- Satellite Dishes: Large concave mirrors are used in satellite dishes to receive signals from satellites. The mirror forms a real image of the incoming signal at the focal point, where it is detected by a receiver.

- Projectors: Spherical mirrors are used in projectors to form an enlarged real image of the projected content. The mirror reflects the light from the source onto a screen, producing a clear and focused image.

2. Formation of Virtual Images:
Virtual images are formed when the reflected rays appear to diverge from a point behind the mirror and cannot be obtained on a screen. Spherical mirrors are used in the following applications to form virtual images:

- Rearview Mirrors: Convex mirrors are commonly used as rearview mirrors in vehicles. They form a virtual image of the objects behind the vehicle, allowing the driver to see a wider field of view.

- Makeup Mirrors: Convex mirrors are used in makeup mirrors to provide a magnified virtual image of the face. The image appears larger and allows for detailed makeup application.

- Security Mirrors: Convex mirrors are used in security mirrors to provide a wide-angle view of areas that are difficult to observe directly. The virtual image formed allows for increased surveillance and prevention of blind spots.

Conclusion:
Spherical mirrors find extensive applications in various fields based on the types of images they can form. Whether it is the formation of real images for telescopes, satellite dishes, and projectors, or the formation of virtual images for rearview mirrors, makeup mirrors, and security mirrors, spherical mirrors play a crucial role in optics and everyday life.
