3. If the spherical mirrors were not known to human beings, guess the consequences.(AS2)
4. Draw suitable rays by which we can guess the position of image formed by a concave
mirror? (AS5)
5. Show the formation of image with a ray diagram when an object is placed on the principal
axis of a concave mirror away from the centre of curvature? (AS5)
6. Why do prefer a convex mirror as a rear-view mirror in the vehicles? (AS7)
III. Higher Order Thinking Questions
1. A convex mirror with a radius of curvature of 3 m is used as rear view mirror for a vehicle.
If a bus is located at 5 m from this mirror, find the position, nature and size of the image?
(AS7)
2. To form the image on the object itself, how should we place the object infront of a concave
mirror? Explain with a ray diagram? (AS5)
