Question

Using a pinhole camera, a student observes the image of two of his friends standing in the sunlight wearing yellow and red shirts, respectively. What will be the colours of the shirts in the image?

Answer 1

1. The colours of the shirts will remain the same.
2. We see them on the screen because the pinhole camera forms the images of the object having the same colour but upside down.
3. So, a yellow shirt will form a yellow image and a red shirt will form a red image.
