Yogita Ingle 5 years, 9 months ago

A pinhole camera is a simple camera, without lens, in the shape of a box. One of the sides has a small hole and it produces an inverted image of the outside world at other side.

The box should be painted black from outside and inside for better clarity.
The object whose image is to be seen should be in bright light.
Smaller the hole, sharper the image.
Temporary Black and White images are formed on the screen if a tracing paper is used. Permanent colored and b & w images can be obtained using photographic films instead of tracing paper.
In the below diagram, two boxes are placed one inside the other. The image of the outer object is created inverted on the inner box translucent screen.

Sidrah Mahvish 5 years, 9 months ago

I cant post the diagram But can sure tell the answer: A pinhole camera works on a simple principle. Imagine you are inside a large, dark, room-sized box containing a pinhole. Imagine that outside the room is a friend with a flashlight, and he is shining the flashlight at different angles through the pinhole. When you look at the wall opposite the pinhole, what you will see is a small dot created by the flashlight's beam shining through the pinhole. The small dot will move as your friend moves his flashlight. The smaller the pinhole (within limits), the smaller and sharper the point of light that the flashlight creates.

Meghna Thapar 5 years, 9 months ago

We observe many things around us having certain properties such as its state (solid, liquid or gas). When one or more properties of a thing become different, we say it has changed or a change has taken place in it. Some important changes that we observe in our everyday life are:

Formation of curd from milk.
Burning of fuels
Cooking of food
Drying of clothes
Rusting of iron.

There must be a cause which brings change in an object like heat, light, electricity, force. Heat causes a change in the state of solid to liquid in case of water.

All changes occurring around us can be categorized into two types – reversible and irreversible.
