Detailed Solution

The above statement is False.
Light travels in a straight line, so whether you pass it through a circular or rectangular hole, the image will be the same because the holes function as pinhole cameras. The electromagnetic radiation that the human eye perceives as light. When nothing is in its path, light moves in a straight line. Light can pass through transparent objects without affecting them. A portion of the light can pass through transparent objects, while opaque objects completely block the light and prevent it from passing through them.
The correct statement would be “When an opaque object blocks the light's path, a shadow is created”. Pinhole cameras can be constructed out of inexpensive materials and used to capture images of the Sun and other brightly lit objects.
