Detailed Solution

The above statement is True.
Typically, shadow size increases with proximity to the object and decreases with distance from the source of light. Therefore, the size of the shadow would decrease as the torch is moved away from the object. The shadow may take on an elliptical shape, but it never takes on a rectangular shape.The shape of the shadow changes when we move the light source away from the object or when we move the light source closer to the object. When we move it away, the shadow will become shorter and thinner until it finally disappears. When we move it closer, the shadow will become longer and wider. Shadows are formed when we place an opaque object between the light source and the screen. Question Image
