Wave Optics Solutions
Get, detailed solutions to the questions of the chapter Wave Optics from NCERT textbooks. The objective is to helping students regarding the pattern of answering the question as per the cbse latest marking scheme.
Some questions of this chapter are given here.
Q. In a Young’s double-slit experiment, the slits are separated by0.28 mm and the screen is placed 1.4 m away. The distance between the central bright fringe and the fourth bright fringe is measured to be 1.2 cm. Determine the wavelength of light used in the experiment.
Q. In Young’s double-slit experiment using monochromatic light of wavelength λ, the intensity of light at a point on the screen where path difference is λ, is K units. What is the intensity of light at a point where path difference is λ/3?
Q. What is the Brewster angle for air to glass transition? (Refractive index of glass = 1.5.)
Q. In a double-slit experiment the angular width of a fringe is found to be 0.2° on a screen placed 1 m away. The wavelength of light used is 600 nm. What will be the angular width of the fringe if the entire experimental apparatus is immersed in water? Take refractive index of water to be 4/3.
