Chapter 33: Q. 2 (page 954)

In a double-slit interference experiment, which of the following actions (perhaps more than one) would cause the fringe spacing to increase? (a) Increasing the wavelength of the light. (b) Increasing the slit spacing. (c) Increasing the distance to the viewing screen. (d) Submerging the entire experiment in water.

Short Answer

Expert verified

Increasing the wavelength of the light.

Increasing the distance to the viewing screen.

Step by step solution

01

Definition of double slit Experiment

Interference from Two Slits Assume the slits are separated by and the viewing screen is located d=1.00cm L=1.20m from the slits in the double-slit interference experiment.

02

Step2:  Action of double slit experiment

As a result, increasing and L increases the perimeter spacing while holding the opposite parameters constant. Similarly, increasing d decreases the perimeter spacing while keeping all other parameters constant. Submerging the experiment in water causes the perimeter spacing to decrease while the opposite parameters remain unchanged, leading to a decrease in fringe spacing. As a result, the solution Increasing the wavelength of the sunshine. Increasing the gap between yourself and also the viewing screen

A Michelson interferometer operating at a 600nmwavelength has a 2.00-cm-long glass cell in one arm. To begin, the air is pumped out of the cell and mirror M2is adjusted to produce a bright spot at the center of the interference pattern. Then a valve is opened and air is slowly admitted into the cell. The index of refraction of air at 1.00atmpressure is 1.00028. How many brightdark-bright fringe shifts are observed as the cell fills with air?

Light of wavelength620nmilluminates a diffraction grating. The second-order maximum is at angle 39.5°. How many lines per millimeter does this grating have?

Two 50-μm-wide slits spaced 0.25mmapart are illuminated by blue laser light with a wavelength of 450nm. The interference pattern is observed on a screen2.0m behind the slits. How many bright fringes are seen in the central maximum that spans the distance between the first missing order on one side and the first missing order on the other side?

Helium atoms emit light at several wavelengths. Light from a helium lamp illuminates a diffraction grating and is observed on a screen50.00cmbehind the grating. The emission at wavelength 501.5nmcreates a first-order bright fringe 21.90cmfrom the central maximum. What is the wavelength of the bright fringe that is 31.60cmfrom the central maximum?

A helium-neon laser (λ=633nm)is built with a glass tube of inside diameter 1.0mm, as shown in FIGURE P33.62. One mirror is partially transmitting to allow the laser beam out. An electrical discharge in the tube causes it to glow like a neon light. From an optical perspective, the laser beam is a light wave that diffracts out through a 1.0-mm-diameter circular opening.

a. Can a laser beam be perfectly parallel, with no spreading? Why or why not?

b. The angle θ1to the first minimum is called the divergence angle of a laser beam. What is the divergence angle of this laser beam?

c. What is the diameter (in mm) of the laser beam after it travels3.0m?

d. What is the diameter of the laser beam after it travels 1.0km?
