[4 marks]

Answer 1

• Pinhole camera is a simple camera used to obtain an image of an object through a small opening. [1 mark]
• Image obtained in a pinhole camera is inverted because the light travels in a straight line. [1 mark]
• Hence, light from the top of the object passes through the pinhole and strikes the tracing paper at the lower end and the light from the bottom of the object passes through the pinhole, striking the upper end of the tracing paper. This causes the inversion of the image. [2 marks]
