Q23) Is the image obtained in a pinhole camera erect or inverted? Give reason for your answer.
Solution:
Image obtained in a pinhole camera is inverted. This happens because the light travels in a straight-line path. Hence light from the upper point of the object when passes through the pinhole and strikes the tracing paper at the lower end and the light from the lower part of the object when passes through the pinhole, strikes the upper end of the tracing paper.
