Suppose two slits, each of width a, are separated by a distance d = 2.5a. Are there any missing maxima in the interference pattern produced by these slits? If so, which are missing? If not, why not?

The analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. Two slits that are 0.200 mm apart produce an interference pattern on a screen such that the central maximum and the 10th bright band are distanced by an amount equal to one-tenth the distance from the slits to the screen. y= ________ d=________ m=_______ L=________

The figure shows a double slit located a distance x = 3.15 m from a screen, with the distance from the center of the screen to a bright fringe given by y. When the distance d between the slits is large compared to the wavelength λ, there will be numerous such bright fringes.  Calculate the distance between adjacent fringes, in centimeters, for 640-nm light falling on double slits separated by 0.0785 mm. You may assume that θ is small.

Finally, perform some conversions of the given information such that all information share the same unit. If two slits 0.100 mm apart are separated from a screen by a distance of 300 mm, then the first-order minimum will be 1 cm from the central maximum. y= ________ d=________ m=_______ L=________

Light with wavelength 2 passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit. The first minimum of the diffraction pattern is at distance d from the middle of the central maximum. Calculate the wavelength of light if D=2.4 m, d =1 mm and w = VAD.Give your answer in nanometers. Answer: Choose...

A monochromatic source of light of wavelength λ, is incident on a slit of width a. Obtain an expression to represent the angle of the 4th diffraction minimum. Hint: Think about Huygens construction with the single slit divided into four equal length sections acting as sources of secondary waves. Write down a general expression for the nth minimum angle. If λ =500 nm, a = 4 μm, determine the angle of the 2nd minimum.

A helium-neon laser (λλ = 633 nmnm) illuminates a single slit and is observed on a screen 1.60 mm behind the slit. The distance between the first and second minima in the diffraction pattern is 3.75 mm . What is the width (in mm) of the slit? Express your answer in millimeters.
