To construct ray diagrams, two rays of light are generally so chosen that it is easy to determine their directions after reflection from a mirror. Choose two such rays and state the path/direction of these rays after reflection from a concave mirror. Use these two rays to find the position and nature of the object placed at a distance of 8cm from a concave mirror of focal length 12cm. You have two lenses A and B of focal lengths +10 cm and -10 cm respectively. Which of the two lenses will form a virtual and magnified image of an object placed 6 cm from the lens?
PLEASE HELP FRIENDS....
