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.

Optical Instruments 1 Magnifying glass or simple microscope and its properties

Find the net deviation produced in the incident ray for the optical instrument shown in figure. (Take refractive index of the prism material as 2.)

Wavelength of light used in an optical instrument are lambda_(1) = 4000 Å and lambda_(2) = 5000Å then ratio of their respective resolving resolving powers (corresponding to lambda_(1) and lambda_(2) ) is
