(a) a concave mirror
(b) a convex mirror
(c) a plane mirror
(d) both concave as well as plane mirror
Correct Answer – (B)
Question 8 :
A student conducts an activity using a concave mirror with focal length of 10 cm. He placed the object 15 cm from the mirror. Where is the image likely to form?
(a) at 6 cm behind the mirror
(b) at 30 cm behind the mirror
(c) at 6 cm in front of the mirror
(d) at 30 cm in front of the mirror
Correct Answer – (D)
Question 9 :
Rahul conducts an experiment using an object of height 10 cm and a concave lens with focal length 20 cm. The object is placed at a distance of 25 cm from the lens. Can the image be formed on a screen?
(a) yes, as the image formed will be real
(b) yes, as the image formed will be erect
(c) no, as the image formed will be virtual
(d) no, as the image formed will be inverted
Correct Answer – (C)
Question 10 :
A student studies that a convex lens always forms a virtual image irrespective of its position. What causes the convex mirror to always form a virtual image?
(a) because the reflected ray never intersects
(b) because the reflected ray converges at a single point
(c) because the incident ray traces its path back along the principal axis
(d) because the incident ray of a convex mirror gets absorbed in the mirror
Correct Answer – (A)
