Kindly give some numerical based questions on the topic "Reflection" with solutions.
Solution :
Some numericals with their solutions are provided below.
1. A divergent lens of focal length equal to 30 cm produces an image of an object of height 4 cm placed at a distance of 30 cm in front of the lens. Find the position of the image formed, nature of the image and the magnification produced by the lens. Draw a ray diagram for the above scenario.
Solution
2. An object of 4 cm height is placed at the distance of 6 cm in front of a concave mirror of focal length 12 cm. Find the position, nature and the size of the image formed.
Solution
3. The radius of curvature of a convex mirror used on automobiles is 20 cm. A bus is coming behind it at a distance of 3.5 m. Calculate (i) the position and (ii) the size of the image relative to the bus. Also, comment on the nature of the image.
