What is the difference between cathode rays and beta rays? When the two are travelling in space, can you make out which is the cathode ray and which is the beta ray?
Asha’s mother read an article in the newspaper about a disaster that took place at Chernobyl. She could not understand much from the article and asked a few questions from Asha regarding the article. Asha tried to answer her mother’s questions based on what she learnt in Class XII Physics.
  1. What was the installation at Chernobyl where the disaster took place? What, according to you, was the cause of this disaster?
  2. Explain the process of release of energy in the installation at Chernobyl.
  3. What, according to you, were the values displayed by Asha and her mother?
White coherent light (400nm - 700nm) is sent through the slits of a Young's double slit experiment (figure.) The separation between the slits is 0.5mm and the screen is 50cm away from the slits. There is a hole in the screen at a point 1.0mm away (along the width of the fringes) from the central line.
  1. Which wavelength (s) will be absent in the light coming from the hole?
  2. which wavelength (s) will have a strong intensity?

A hole of radius r1 is made centrally in a uniform circular disc of thickness d and radius r2. The inner surface (a cylinder of length d and radius r1) is maintained at a temperature $\theta_1$ and the outer surface (a cylinder of length d and radius r2) is maintained at a temperature $\theta_2(\theta_1>\theta_2).$ The thermal conductivity of the material of the disc is K. Calculate the heat flowing per unit time through the disc.
