A thin layer of liquid methylene iodide (n = 1. 756) is sandwiched between two flat parallel plates of glass (n = 1. 518). What would be the minimum thickness of the liquid layer if normally incident light with lambda = [01]nm in air is to be strongly reflected? A thin layer of oil (n = 1. 252) is floating on water. What Is the minimum thickness of the oil in the region that strongly reflects light with a wavelength of [02]nm (in air)? Use n = 1. 333 for the index of refraction of water. Be careful about using Eqs. [24. 9] and [24. 10] in the textbook. Read the paragraph following Light of wavelength [03]nm falls on a 0. 427-mm-wide slit and forms a diffraction pattern on a screen 1. 46 m away, (a) Find the angle theta for the direction at which the first dark band on either side of the central maximum occurs, (b) Find the distance on the screen from the central maximum to the first dark baud on either side of it. Use the small-angle approximation for both parts of this problem.

Explanation / Answer

1 Ans:-

Presumably strong reflection is referring to the set-up achieving constructive interference between rays reflected off the top and bottom of the liquid layer.

There is a phase shift of
