Usually, when the school began, there was a great bustle. The noise could be heard out in the school. Students opened and closed their desks. They repeated the lessons together very loudly. They kept their hands over their ears to understand better. The teacher would go on rapping the table with his great iron ruler.

  (x – 1, y + 3) = (2, x + 4) 

So, x - 1 = 2

x = 2 + 1 = 3

and y + 3 = x +4

y + 3 = 3 + 4

y + 3 = 7

y = 7 - 3

y = 4

When image is virtual and erect then the image distance will be positive but when it is real and inverted then the image distance will be negative. In concave mirror only in one case when object is between pole and focus then the image distance will be positive. In convex mirror image distance is always positive.

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

Lenses: A lens is a part of a reflecting material like glass or plastic but curved from both sides. Lenses are unlike mirrors that have a reflecting surface only on one side. Depending upon its shape a lens can be categorized as:

  • Convex Lens - A Convex Lens is curved outwards. It is thicker in the centre and narrows down at the edges. It merges the light rays passing through it at a certain point. Therefore, it is also called a Converging Lens.

  • Concave Lens - A Concave Lens is curved inwards. It has wider edges and a thinner centre. It reflects back the light that travels through it in different directions. Therefore, it is also called a Diverging Lens.

He was inspired by the teachings of the Buddha
