i) a only ii) b and c both

iii) b and d both iv ) c and d both

Q6.4 After few days that mirror becomes dirty. During cleaning, Rajesh held the mirror

inside the water. So, what should be the change in the focal length of the mirror?

a) increases b) decreases

c)no change d) none of the above

Q6.5 One day Rajesh was going to his office in his car. While driving his car, he saw

another car behind him through his rear-view mirror as shown in the figure. He saw

that the car coming from behind was at a distance of 4.5 m. If the radius of curvature

of the mirror used as a rear view mirror in a moving car was 2.0 m. Calculate the

position of the image of the car behind him.
