Ques. 91JEE Main 2024, 30 January (Evening Shift)

In an experiment to measure the focal length (f) of a convex lens, the magnitude of object distance (x) and the image distance (y) are measured with reference to the focal point of the lens. The y-x plot is shown in figure. The focal length of the lens is cm. [figure]

Ques. 92JEE Main 2024, 29 January (Morning Shift)

  1. -45 cm
  2. -15 cm
  3. 45 cm
  4. 15 cm
Ques. 93JEE Main 2024, 29 January (Morning Shift)

A biconvex lens of refractive index 1.5 has a focal length of 20 cm in air. Its focal length when immersed in a liquid of refractive index 1.6 will be:

  1. -16 cm
  2. +16 cm
  3. +160 cm
  4. -160 cm
Ques. 94JEE Main 2024, 29 January (Evening Shift)

If the distance between object and its two times magnified virtual image produced by a curved mirror is 15 cm, the focal length of the mirror must be:
