The linear magnification produced by a lens is defined as the ratio of the: I. Size of the image to the size of the object II. Size of the lens to the size of the object III. Size of the lens to the size of the image
Correct answer: A. I only
- A. I only
- B. II only
- C. III only
- D. II and III only
- E. I, II and III
Explanation
The magnification is defined as the ratio of the size of the image to the size of the object.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
