Emergent ray: Deviates Reflects Disappears Undeviated 2 / 10 A convex lens used as magnifier produces image that is: Real & inverted Virtual & erect Real & same size Diminished 3 / 10 A ray passing through the optical centre of a lens emerges: Deviated Reflected Undeviated Absorbed 4 / 10 A convex mirror of focal length 15 cm forms image at 10 cm. Object distance is: –30 cm –15 cm –10 cm –20 cm 5 / 10 A ray passing through focus of convex lens emerges: Parallel to axis Through C Through pole Random 6 / 10 A convex lens has focal length 20 cm. Power of the lens is: 2 D –5 D 0.2 D 5 D 7 / 10 Power of lens is negative when it is: Convex Plane Concave Thick 8 / 10 If refractive index increases, speed of light: Increases Decreases Remains same Becomes zero 9 / 10 A concave lens always forms image that is: Real Virtual & diminished Inverted Same size 10 / 10 If image distance equals object distance in concave mirror, magnification is: –1 1 0 2 Your score is 0% Restart quiz
