Detailed explanation-1: -Rosita shined a flashlight down a hallway. The light could be seen along the hallway but not around the corner. Which sentence best explains this? Light can be reflected.
Detailed explanation-2: -Once light is produced, it will travel in a straight line until it interacts with a medium(s). Shadows are evidence of light traveling in straight lines. Some objects, that are opaque, block light so that it cannot reach the surface where we then see the shadow.
Detailed explanation-3: -The main reason why light moves in straight lines are because it is a wave and prefers to travel the smallest distance between the two points. Light, however, can diverge from a straight trajectory when it strikes certain obstructions. Diffraction is a popular name for this phenomenon.
