Explanation:
Light travels in straight lines. In particular, light travels in straight lines through the pinhole. ... A pinhole makes an image because all of the light that leaves one point on the pin and goes through the pinhole arrives at one point on the screen, (regardless of where the screen is.)
The image is very dim because the pinhole is so small, but you can see it if the room is very dark. ... The reason a normal camera uses a lens rather than a pinhole is because the lens creates a much larger hole through which light can make it onto the film, meaning the film can be exposed faster.
