07 PHYSICS Holiday Homework Class XII

Chapters: Ray Optics and Optical Instruments Wave Optics

Q1.Determine if the densities of different materials change the speed of light. Also determine if changing the incidence angles or the temperatures of the materials, would change the velocity of the light through the material. Use transparent materials like oil, sugar and salt solutions of different concentration and temperature by projecting a laser beam through these solutions kept in glass containers at various angles (take photographs ) and calculate the index of refraction of each material at a 300, 450 and 600 degree angle. The photograph will help to measure the incidence and refracted angle. Use Snell’s Law. Repeat this procedure for each material at two different temperatures (use clinical thermometer available at home).Draw graphs showing the variation of Density w.r.t Refractive Index and variation of Temperature with respect to Refractive Index for each test. Or Make your own double slit experiment and diffraction experiment at home using a laser pointer and house hold materials. Write down the steps along with the photographs. Repeat these experiments for slits of different widths and record your observations. What do you conclude from the following experiment ?

ClassXII (ComputerScience) Q1) Write a Python program to create a game named “Guess the Number”. The player will be given 5 chances to guess the correct number which computer has generated in the range 11to20. Points will be given based on the number of chances the player has taken to guess it right, if guessed in the first chance then five, second then 4and soon. With every wrong answer, hint should be given about the number. The program should continue as many times as the player wants every time with a new number in the range 11to20. Display proper output showing Player’s name, points and number of chances taken to guess the correct number. Q2) A Mersenne number is a number in the form 2n-1i.e.if n is 2 then mersenne number will be 3. Write a program inPython that will pass n to a function named mersenne() and the function returns nth Mersenne number. Q3) All worksheets and assignment quiz should be completed given through Google classroom.
