9) Monochromatic coherent light shines through a pair of slits. If the distance between these slits is decreased, which of the following statements are true of the resulting interference pattern? (There could be more than one correct choice.)

A) The distance between the maxima stays the same.

B) The distance between the maxima decreases.

C) The distance between the minima stays the same.

D) The distance between the minima increases.

E) The distance between the maxima increases.

Expert Solution

apply Y = mLR/d

where d is slit width and Y is fringe width

so here if d decreses, Y increses

so correct answers are

D) The distance between the minima increases.

E) The distance between the maxima increases.

A pair of narrow slits that are 1.8 mm apart is illuminated by a monochromatic coherent light source. A fringe pattern is observed on a screen 4.8 m from the slits. If there are 5.0 bright fringes/cm on the screen, what is the wavelength of the monochromatic light? A) 550 nm B) 600 nm C) 650 nm D) 700 nm E) 750 nm

Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference minima at \pm 35.09 degrees on either side of the central bright spot. You then immerse these slits in a transparent liquid and illuminate them with the same light. Now you find that the first minima occur at \pm 19.48 degrees instead. a) What is the index of refraction of this liquid? Express your answer using four significant figures.

In Young’s experiment, monochromatic light of wavelength 600 nm shines on two slits separated by 0.3 mm, producing an interference pattern on a screen that is 2.0 m away. You put a thin sheet of glass (n = 1.5) at the top slit and you observe a dark fringe the central location of the screen. Furthermore, the fourth bright spot on both sides of the central location is missing. (a) Sketch the resulting interference pattern. Precisely state the spacing between...

A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness L and index of refraction n=1.5 . The wavelength of the laser light in vacuum is L/10 and its frequency is f In this problem, neither the constant c nor its numerical value should appear in any of your answers. (1)How long does it take for a short pulse of light to travel from one end of the glass to the other?
