Answer 2

Answer:

The learner should slide the inner box forward or backward to gain a clear image.

Explanation:

The clarity of the picture obtained reduces when the size of the hole in a pinhole camera is increased. In addition, the picture thickens and blurs. This is due to the fact that as the size of the hole rises, so does the amount of light entering the box, interfering with the creation of the picture.

What exactly is a Pinhole Camera?

The pinhole camera is the most basic type of camera. There is no lens on it. To obtain the clearest image possible, it simply uses a tiny-opening (a pinhole-sized opening) to focus all light rays within the smallest possible area.

How to make a Pinhole Camera?

You can make a simple pinhole camera out of components you probably already have at home. Here are the step-by-step directions for creating a pinhole camera.

1. Take a small box, such as shoebox or a coffee can.
2. To make the box lightproof, paint it totally black.
3. Determine the appropriate distance between the film and the light source and cut a circular pinhole in the bottom of the box.
4. Cut a piece of thick black chart paper into a shutter (2 x 2 inches ideal).
5. To keep the shutter in place, wrap it in strong duct tape.
6. Control the shutter flap and light entering the box with a light adhesive.
7. Make a cardboard viewfinder.

What are the Characteristics of Pinhole Camera Image?

1. The picture may be used to examine the rectilinear propagation of light.
2. The produced picture is much smaller in size than the actual thing.
3. As the picture on the screen is obtained, a genuine image is obtained.
4. The picture has been inverted on both the x and y axes.
