Application
Justification
1
Concave
Dentist Mirro
Virtual,Erect and Magnified Image
2
Convex
Street light
Diverge the light rays hence wider field of view is possible
3
Concave
Solar Furnace
Converages light rays from a distance source like sun
4
Convex
Rearview Mirrors
Virtual, erect and enlarged images are formed

A.

1,2,3 and 4

B.

Only 1

C.

Only 1 and 2

D.

Only 1,2 and 3

Correct option is D

Correct Answer: D

Explanation: In the table, the information is completely correct for the following rows:

  • Row 1: Concave mirror used as a Dentist mirror to produce a virtual, erect, and magnified image, which is correct.
  • Row 2: Convex mirror used for Street light application, where it diverges light rays, providing a wider field of view, which is correct.
  • Row 3: Concave mirror used as a Solar furnace, converging light rays from a distant source like the sun, which is also correct.

However, Row 4 is incorrect because the statement about Convex mirrors forming virtual, erect, and enlarged images is not true. Convex mirrors always produce virtual, erect, and diminished images, not enlarged ones.

Information Booster:

  • Concave mirrors (in Row 1 and 3) are used for magnification and focusing light, which is why they are used in applications like dental mirrors and solar furnaces.
  • Convex mirrors (in Row 2 and 4) are often used in applications requiring a wide field of view, such as streetlights and rearview mirrors. They produce diminished, virtual, and upright images.
