If a ray of light passes through the optical center of a lens, what happens to the ray?
Correct Answer: The ray continues in a straight line.
- Step 1: Understand what a ray of light is. A ray of light is a straight line that represents the path of light.
- Step 2: Know what an optical center of a lens is. The optical center is the middle point of the lens where light can pass through without bending.
- Step 3: When a ray of light reaches the optical center of the lens, it is not affected by the lens's shape.
- Step 4: Since the ray passes through the optical center, it continues to travel in a straight line.
- Step 5: Therefore, the ray of light does not bend or change direction when it passes through the optical center.
- Optical Center of a Lens – The point in a lens where light rays passing through are not refracted, allowing them to continue in a straight line.
