Which of the following is NOT a difference between shadows and mirror image?
Both can form from the light source only
The similarity between a shadow and an image is that neither of them can exist without light. However, there are some differences between shadows and images. Shadows are black, whereas images are colourful. Shadows of objects placed in the sun change in length with the position of the sun through the day. Your shadow will be at its longest at dawn and dusk, whereas it will be at its shortest at noon. An image in a plane mirror doesn't change in size at all. It is always of the same size as that of the object. An image in a mirror can be seen without a screen, whereas it is mandatory to have a screen to form a shadow.
