why pinhole camera are showing inverse image?
riddhi4697:
Because light travels through air in a nearly perfectly straight line. The light travels from the top of the tree, straight through the pinhole, and straight to the BOTTOM of the image. Thus theimage is inverted. Left and right arereversed for the same reason.

The image is very dim because thepinhole 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.

Light always travels in a straight line. So the light from the top of an object passes through the pinhole, continues in a straight line, and ends up at the bottom, on a screen. Similarly the light from the bottom of the object travels through the pinhole, continues in a straight line, and ends up at the top, on the screen. Hence the image looks inverted.
