Question
Screen used in pin hole camera is
A. Transparent
B. Translucent
C. Opaque
D. None of these
Solution
The screen used in a pinhole camera is C. Opaque.
Here's why:
A pinhole camera works on the principle of image formation. When light passes through a small hole (the pinhole), it forms an image on the other side. For us to see this image, we need a surface that doesn't allow light to pass through - an opaque surface.
If the screen were transparent, the light would pass through and no image would be formed. If it were translucent, some light would pass through and the image would be blurred. Therefore, the screen must be opaque to clearly see the image.
