1) In a single-slit diffraction experiment, the width of the slit through which light passes is

reduced. What happens to the width of the central bright fringe?

A) It becomes narrower.

B) It becomes wider.

C) It stays the same.

D) Its behavior depends on the wavelength of the light.

2) A single-slit diffraction pattern is formed on a distant screen. Assuming the angles

involved are small, by what factor will the width of the central bright spot on the screen

change if the slit width is doubled?

A) It will become eight times as large.

B) It will double.

C) It will become four times as large.

D) It will be cut to one-quarter its original size.

E) It will be cut in half.

3) A light beam shines through a thin slit and illuminates a distant screen. The central

bright fringe on the screen is 1.00 cm wide, as measured between the dark fringes that

border it on either side. Which of the following actions would decrease the width of the

central bright fringe? (There may be more than one correct choice.)

A) increase the wavelength of the light

B) increase the width of the slit

C) decrease the wavelength of the light

D) put the apparatus all under water

E) decrease the width of the slit

4) A lens is designed to work in the visible, near-infrared, and near-ultraviolet. The best

resolution of this lens from a diffraction standpoint is

A) indeterminate.

B) in the visible.

C) in the near-ultraviolet.

D) the same for all wavelengths.

E) in the near-infrared.

5) If the diameter of a radar dish is doubled, what happens to its resolving power,

assuming that all other factors remain unchanged?

A) The resolving power doubles.

B) The resolving power is reduced to 1/4 of its original value.

C) The resolving power is reduced to 1/2 of its original value.

D) The resolving power quadruples.

E) The resolving power does not change unless the focal length changes.

6) A single slit forms a diffraction pattern, with the first minimum at an angle of 40.0° from

central maximum, when monochromatic light of 630-nm wavelength is used. The same

slit, illuminated by a new monochromatic light source, produces a diffraction pattern

with the second minimum at a 60.0° angle from the central maximum. What is the

wavelength of this new light?

A) 425 nm B) 450 nm C) 500 nm D) 525 nm E) 475 nm

7) A single slit forms a diffraction pattern, with the first minimum at an angle of 40.0° from

central maximum, using monochromatic light of 490-nm wavelength. What is the width

of the slit?

A) 700 nm B) 668 nm C) 731 nm D) 637 nm E) 762 nm

8) A slit of width 0.010 mm has light of frequency 5.0 × 1014 Hz passing through it onto a

screen 60 cm away. How wide is the central maximum? (c = 3.00 × 108 m/s)

A) 0.12 cm B) 0.90 cm C) 7.2 cm D) 1.8 cm E) 3.6 cm

9) A single slit, which is 0.050 mm wide, is illuminated by light of 550 nm wavelength.

What is the angular separation between the first two minima on either side of the central


A) 0.36° B) 0.73° C) 0.54° D) 0.63° E) 0.47°

10) Light of wavelength 687 nm is incident on a single slit 0.75 mm wide. At what distance

from the slit should a screen be placed if the second dark fringe in the diffraction pattern

is to be 1.7 mm from the center of the diffraction pattern?

A) 0.47 m B) 0.93 m C) 1.1 m D) 1.9 m E) 0.39 m is an online academic writing platform that provides extensive assistance to graduate school students as they work through their research projects, papers and dissertations. gives students access to experienced professionals who can provide the help they need in a timely and efficient manner. The service offers a wide range of services, including editing, proofreading, formatting, researching and more that can give students the confidence they need to write the perfect paper or dissertation for their chosen subject matter.

Services Offered by offers a wealth of different services designed to make research projects easier for graduate school students. These include editing, proofreading, formatting and researching services, all tailored specifically for graduate-level studies such as PhDs or Master’s degrees in any field from business administration to engineering or even psychology – all with the aim of helping busy students find success in their academics without having to sacrifice other important commitments like family time or work hours towards earning a living wage outside of college hours.

The Benefits of Using
Using gives you access to experts from all over the world who are highly qualified and experienced in helping graduate-level students to complete successful projects in various fields quickly and efficiently – something that would otherwise be difficult, if not impossible, given tight deadlines associated with most Ph.D./Master’s degree programs today. Moreover, using this platform makes it easier for students to keep up with multiple research tasks simultaneously since there are so many different experts available on tap at any one time – no longer will you have to put off studying one topic while focusing on another because of lack of resources! Additionally, having access to professional editors, proofreaders, but also formatters means that quality control standards aren’t sacrificed when finishing major pieces – since these individuals understand what makes up good academic writing better than anyone else and can offer guidance on how best one should go about making improvements along those lines. Finally, there is also an added cost-saving benefit associated with utilizing Graduate Writer Help compared to hiring an independent contractor (which could potentially run into thousands depending on length/complexity).
This service allows users only pay for what students need, which tends to be much lower overall because customers pay per hour rather than project basis, thus resulting to greater financial flexibility, especially for those just starting out postgraduate studies looking to conserve some pennies here there whenever possible!
