Question

1. Draw the ray diagram in each case to show the position and nature of the image formed when the object is placed:

(1) between the pole P and focus F of a concave mirror

(ii) at 2F of a convex lens

(iii) at infinity of a concave lens

2. For which position of the object does a convex lens form a virtual and erect Explain with the help of a ray diagram

3. Show refraction through a glass slab with the help of a labelled diagram image?​

Answer 1
