Optical Instruments 2 compound microscope and its properties

Geometrical Optics Part-2

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.

The present value of an optical instrument is Rs. 20000. If its value will depreciate 5% in the first year, 4% in the second year and 2% in the third year, what will be its value after 3 years? R s .16534.5 b. R s .16756.5 c. R s .17556.8 d. R s .17875.2

Wavelength of ligh used in an optical instrument are lamda_ =4000A and lamda_2=5000A , then ratio of their respective resolving powers (corresponding to lamda_1 and lamda_2 )
