1 . why are circular patches of light seen under a tree during day time?
2.Why does a bird flying in the air not cast a shadow?Explain
3.A frog is sitting 85cm in front of a plane mirror M.If the mirror is now moved 0.20 m away from the frog , how does the image of the frog shift from its previous image?
4.On a plane mirror , a ray of light falls at a glancing angle of 30°,then

4.On a plane mirror , a ray of light falls at a glancing angle of 30°,then
- through what angle has the ray been deviated?
- If the angle of incidence is increased by 10°,What would be the increase in the angle of reflection?
- What should be the angle of incidence for the incident & reflected rays to form an angle of 65.5°
