Question

Which of the following is not a characteristic of a pinhole camera?
A. It Produces an Inverted Image.
B. It Works on the Principle of Rectilinear Motion of light.
C. It is Inexpensive to make.
D. The image produced is black and white.

Answer 1

Hint : The pinhole camera is a normal camera without a lens but it has a tiny Aperture so it is called the Pinhole Camera. It works on the principle of the rectilinear motion of light.It produces the inverted image on the opposite side of the box when light passes through the aperture.

Complete step-by-step solution:
The image formed is upside down that is Inverted compared to the Object. The formed image is real because it can be formed on the screen, and of the same color as the object.
The generated Image can be smaller than the original object, equal to the object, or larger than the object. this size of the object depending on the distance between the object from the pinhole camera. It is very inexpensive to make.
It works on the principle of the rectilinear motion of light.
The Pinhole photographs have infinite depth of field, there is no lens distortion, and wide-angle images remain rectilinear. the image generated by the pinhole camera is smaller than the actual image
The formed images can be used in the Analysis of rectilinear propagation of light. The pinhole camera generates the inverted images on the opposite side of the box which is known as the camera obscura effect.
Option D-The image Produced is Black and white

Note: It can capture a movement over a long period of time
It can be used in surveillance because they are difficult to detect.
The camera obscura effect is a natural optical phenomenon.
