light passes through a single slit of width 8.77 x 10^-6 m. The second (m = 2) light diffraction minimum occurs at an angle of 5.62°. What is the wavelength of the light, in nanometers?

Expert Solution

The single slit diffraction: When light passes through a single slit whose width is of the same order as wavelength of the light, then we can observe a single slit diffraction pattern on a screen.

At minimum we see dark fringes due the destructive interference of light. Dark fringes in the diffraction pattern of a single slit are found at angles for which ..............................

where is an integer, = 1, 2, 3, ... . For the first dark fringe we have m=1.

Now coming to the question

given =2 (2nd dark fringe means second diffraction minimum) , ,

using equation

so

Light from a He-Ne laser (wavelength 633nm) passes through a single slit of width 25μm. At the screen a distance away, the intensity at the center of the central maxima is 8.25 W/m^2. a. Draw a clear diagram showing the slit and the intensity pattern seen on the screen. Label key quantities and key features. b. Find the maximum number of totally dark fringes (minima) seen on the screen. c. At what angle does the dark fringe (minima) that is...

Red light of wavelength 675 nm is incident on a slit of width 4.56 × 10−6 m. An observing screen is placed 1.50 m from the slit. 9a) Find the distance between the third order dark fringe and the central bright fringe (in meters). 9b) If you replaced the single slit with two slits centered on the former position of the single slit, what would the separation between the two slits need to be in order for the second order...

In a double-slit experiment, light with a wavelength λ passes through a double-slit and forms an interference pattern on the screen at a distance L from the slits. What statement is true for the resulting interference pattern if the frequency of the light increases? OPTIONS: The distance between maxima stays the same.T he distance between maxima increases. The distance between maxima decreases. Not enough information given.

Light of unknown wavelength passes through a double slit, yielding both double slit and diffraction patterns on a screen that is 1 m away from the slits. You see that the 9th double-slit maximum coincides with the 2nd single-slit diffraction minimum. You also observe that the first diffraction minimum is located 3 cm from the central axis on the screen. (a) What is the ratio of double-slit separation to single slit width, d/a? (b) If d = 72 µm, what...

In procedure 2: suppose red light passes through a double slit and falls on a screen. In the diffraction pattern, the distance from the central maximum to the first maximum is 5 mm. a) The distance from the first minimum (dark spot) to the second minimum in the diffraction pattern is between 7.5 mm and 10 mm less than 2.5 mm more than 10 mm between 2.5 mm and 5 mm exactly 2.5 mm between 5 mm and 7.5 mm...

Width of Peak (cm): 1.6 Width of Slit for Single Peak: 2.3 The width of the center peak (w) can be calculated using the equation w = 2λL/ a where a is the width of the slit. Use this equation to determine the width of the slit that caused the diffraction pattern. Show your work. I am confused as to what I am finding since I do not have L. I have going backwards λL = 1.84. If someone could...

An experiment is conducted in which red light is diffracted through a single slit.Then, each of the following alterations to the original experiment is made, one at a time, and the experiment is repeated. After each alteration, the experiment isreturned to its original configuration.A The slit width is halved.B The distance between the slits and the screen is halved.C The slit width is doubled.D A green, rather than red, light source is used.E The experiment is conducted in a water-filled...

1. Instead of blocking out all light except what passes through a slit to get an interference pattern, we can block out only the slit and get an equivalent pattern. This is called Babinet’s Principle. You effectively saw Babinet’s Principle when you put the hair in front of the laser. Describe how you could use “single slit diffraction” to measure the size of the hair? 2. Frequently, photographs of bright lights will result in a “star” effect on...
