Class 12 Physics | Chapter 9 Ray Optics and Optical Instruments | Important Questions & Quick Revision | Part 3

A: Ray optics assumes that light travels in a straight line which is disapproved by diffraction effects, yet the ray optics assumption is so commonly used in understanding location and several other properties of images in optical instruments. R: Typical sizes of apertures involved in ordinary optical instruments are much larger than the wavelength of light.

Four rays of light above the optic axis (parallel to it) and their path after striking an optical system are shown in column-I . Match the corresponding optical instrument from column-II:
