In Youngs experiment, when the distance between slit and screen is doubled, while separation of slit is halved, then fringe width will be: Correct Answer <span style=" ">4 times</span>

CONCEPT:

  • Young's Double Slit Experiment (YDSE): Monochromatic light (single wavelength) falls on two narrow slits S1 and S2 which are very close together act as two coherent sources when waves coming from two coherent sources, (S1, S2) superimposes on each other, an interference pattern is obtained on the screen.
    • In Young's Double Slit Experiment alternate bright and dark bands obtained on the screen. These bands are called Fringes.

Mohan traveled five cities (A, B, C, D and E) starting from home by a car which has a mileage such that the car can travel 10 km in 1 liter petrol. Distance between city A and B is twice the distance between home to city A. Distance between city B and C is thrice the distance between home to city A. Distance between city C and D is 100. Distance between city D and E is 1.5 times than the distance between B and C. Average distance traveled by Mohan was 41 km between five cities. Find how much petrol was needed by Mohan to travel from city B to D.
