Final answer:
The statement is true. As the light source moves farther away from the wall screen, the light spot will appear larger and dimmer.
Step-by-step explanation:
The statement is true. As the light source moves farther away from the wall screen, the light spot will appear larger and dimmer. This is because the farther the light travels, the more it spreads out, resulting in a larger and less intense spot on the wall.
This phenomenon is called diffraction. When light encounters an obstacle or passes through a narrow opening, it bends and spreads out, creating a pattern of bright and dark areas on a screen or wall. The size and intensity of the light spot depend on the distance between the light source, the obstacle, and the wall screen.
For example, if you shine a flashlight at a wall from a close distance, the light spot will be small and bright. But if you move the flashlight farther away, the light spot will become larger and less intense.
