Question

The image formed in a pinhole camera is real.
A. True
B. False

Answer 1

Hint: Here we will do the practical using the pin-hole camera and with the help of the ray diagram will observe the image formed from it. The pinhole camera is the simple camera in the form of the box has a very small hole in one of its sides without the lens which creates image on the other side.

Complete step by step answer:

As shown in the above figure, take an ordinary hollow rectangular cardboard box, painted black from outside for better clarity and with the small hole in the middle of one of its sides of the box.
The size of the hole should be as small as possible, should be equal to the size of the head of the pin. Image formed is related to the size of the hole - smaller the hole, the image is sharper. With the increase in the size of the hole, the image will get more unclear and blurred on the screen.
The light ray which comes from the object goes towards the bottom of the pinhole camera screen through the hole. In this particular way light coming in the particular direction from each point of the object, will go through the pinhole and block the light going in another direction which leads to the formation of an inverted and real image.
Thus, the image formed by the pin-hole camera is real.
Hence, from the given multiple choices - the option A is the correct answer.

Note- Always remember the characteristics, the types of the image, nature and the size of the image produced by placing the object at different distances with lenses and without lenses. Remember the difference between the lenses and the image formed by it.
