Which of the following is an example of rectilinear propagation of light?
- Beams of light in car headlights that appear to travel in straight lines (correct)
- Reflection of light off a curved mirror
- Refraction of light through a prism
- Scattering of light by a rough surface
What happens when the path of light is blocked by an opaque object?
What happens when the path of light is blocked by an opaque object?
- It bends the light beams around the object
- It reflects the light back in the opposite direction
- It causes the light beams to scatter in all directions
- It prevents the light beams from passing through, producing shadows (correct)

Study Notes
Rectilinear Propagation of Light
- Rectilinear propagation of light refers to the phenomenon where light rays travel in a straight line.
Examples of Rectilinear Propagation of Light
- An example of rectilinear propagation of light is when light travels from a lamp to a wall.
Obstruction of Light
- When the path of light is blocked by an opaque object, the light is obstructed and cannot pass through.
Speed of Light
- Light rays travel at a speed of approximately 299,792,458 meters per second in a straight line.
