Question

For a convex mirror shown which ray is drawn incorrectly? The focal point F and center of curvature C are indicated. A. A B. B C. C E, All four rays are drawn correctly. Starting with real object, which statement is FALSE about the image formed by a single mirror? A. A concave mirror can produce a virtual, upright, enlarged image. B. For a concave mirror an object has to be placed between the focal point and the mirror in order to form a virtual image. C. A convex mirror always produces a virtual, upright, reduced image. D. A concave mirror can produce a virtual, upright, reduced image. E. A concave mirror can produce a real, inverted, reduced image. 7. A diverging lens (f_1 = -30 cm) and a converging lens (f_2 = +30 cm) are separated by 10 cm as shown below. If an object is placed 15 cm to the left of the diverging lens, where is the final image formed by this lens combination? A. 60 cm to the left of the converging lens B. 30 cm to the left of the converging lens C. 30 cm to the right of the converging lens D. 60 cm to the right of the converging lens E. 120 to the right of the converging lens

Explanation / Answer

according to law of reelction

all the 4 rays drawn are correctly

any ray paralle to the principal axis,it appeares passing through the Focus

any ray passing through pole of the mirror makes equal angles after reflection

any ray passing through C,passes undeviatedly

any ray passes through focus,after reflection it passes parallel to the principal axis

so the answer is E) all four rays are drawn correctly
