HC Verma Solutions Vol 1 Chapter 20 Dispersion And Spectra

HC Verma Solutions Vol 1 Chapter 20 Dispersion and Spectra gives students the opportunity to develop better analytical and problem-solving skills required to tackle even the most difficult questions discussed in this chapter. Some of the questions that students come across are related to the deviation of rays when the refractive angle, the refractive index is given, dispersive power and angular dispersion and more. We have provided the solutions in a very readable and easy format to increase the understanding of concepts and have a great learning experience. Students will learn to solve problems such as:

  • Finding the deviation, angular dispersion when multiple prisms are combined together.
  • They will deal with problems on finding the angular dispersion of rays depending upon the positioning of the prisms whether it is similarly directed or oppositely directed.
  • Questions on various types of light passed over a medium such as white light, yellow ray, etc.

In essence, the HC Verma Solutions provided will help students study smartly and secure better grades in the exams especially competitive ones like JEE.

With the solutions, students will also be able to increase their understanding of topics like;

  1. Dispersion
  2. Dispersive Power
  3. Dispersion without Average Deviation and Average Deviation without Dispersion
  4. Spectrum
  5. Kinds of Spectra
  6. Ultraviolet and Infrared Spectrum
  7. Spectrometer
  8. Rainbow

Important Question In Chapter 20

1. Is it possible to pass a beam through three identical prisms? Will it emerge un-deviated or undispersed? Give your comments.

2. State whether the focal length of a lens depends on the colour of the light used or not? What happens in the case of a mirror?

3. What will happen to the dispersive power If a glass prism is dipped in water? Will it;

(a) remain the same (b) increases (c) decreases (d) may increase or decrease

4. Can you name which quantities of the lens depend on the wavelength or wavelengths of the incident light?

(a) Chromatic aberration Power (b) Radii of curvature (c) Power (d) Focal length

5. Why is the incident light passed through a narrow slit that is placed in the focal plane of an achromatic lens?

(a) Intensity is increased (b) One colour is passed at a time (c) There is less diffraction (d) More number of parallel beams pass through the lens
