b) Describe Young’s Double Slit experiment and understand the concept of fringe spacing, dark and bright fringes.
c) Explain diffraction grating and solve problems using the formula d sin n .
d) Explain the basic principle of Optical Fiber
A sonar depth finder in a boat uses sound signals to determine the depth of water. Fourseconds after the sound leaves the boat it returns to the boat because of reflection fromthe bottom. Assume the speed of sound in water is 1,460 meters per second. The depth of the water is, in meters, :
