Lower Sec Science · Secondary 1 · Hard · Shadows
A torch shines on an opaque ball placed in front of a wall. A dark region is seen on the wall. Using the idea that light travels in straight lines, what is this dark region and why is it formed?
- It is a shadow because the ball blocks light that travels in straight lines.
- It is a reflection because light bounces off the wall.
- It is a refraction pattern because light bends around the ball.
- It is a bright spot because light passes through the ball.
