Answer 2

☆Answer :-

=> Pinhole Camera :-

→ Definition :-

A pinhole is just a box with a very tiny hole one one of its sides.

→ Working :-

When the light falls on the hole of the pinhole camera, an inverted image is formed on the side opposite to the hole. The size of the image depends on the distance between the object and the pinhole. If the size of the image is increased, then the size of the image decreases. If distance is decreased, the size of the image increases.

→ Example :-

The human eye acts very much like a pinhole camera.

→ Required Materials :-

• Box
• Scissors
• Tape
• Needle
• Sand Paper
