Assessment Problems 7
1. Parallel light rays strike the left side of a concave lens and pass through. Why don’t the light rays come to a focus on the right side of the lens?
Answer: When the light rays pass through a concave lens, the rays diverge rather than converge at a point on the right side of the lens.
2. A light ray strikes a plane (smooth) mirror at an angle of 00. What is the value of the reflected angle?
Answer: The reflected angle is back along the direction of the incident ray or the angle of reflection is also 00.
3. Knowing that parallel light rays change direction after passing through a convex lens and converge at the focal point, make a ray drawing showing the formation of the image of a candle located to the left of the focal point on the candle’s side of the lens.
