A diffraction pattern is produced on a screen 1.40 m from a single slit, using monochromatic light of wavelength 500 nm. The distance from the center of the central maximum to the first order minimum is 3.00 mm. Assume that the first order maximum is halfway between the first and second order minima.  Calculate the slit width.

Monochromatic light (wavelength = 455 nm) is incident perpendicularly on a single slit (width = 0.56 mm). A screen is placed parallel to the slit plane, and on it the distance between the two minima on either side of the central maximum is 2.1 mm. (a) What is the distance from the slit to the screen? (Hint: The angle to either minimum is small enough that sin ≈ tan 9.) (b) What is the distance on the screen between the first minimum and the third minimum on the same side of the central maximum? (a) Number 120 (b) Number i 1.8 Units Units cm mm

In a double-slit interference experiment, the wavelength is 737 nm, the slit separation is 0.180 mm, and the screen is 33.0 cm away from the slits.  What is the linear distance between the sixth order maximum and the third order maximum on the screen in millimeters?

In an interference experiment using a monochromatic source emitting light of wavelength 1, the fringes are produced by two long, narrow slits separated by a distance d. The fringes are formed on a screen which is situated at a distance D >> d.Write down an expression for the fringe width w. Please use "*" for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. Use "lambda" (without the quotes) for 1 in the equation box. For example, use d*lambda for d2. Please use the "Display response" button to check you entered the answer you expect. w=

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=________

A student performs a standard two-slit interference experiment and carefully sketches the observed interference pattern. The red colored pencil used by the student may not precisely match the actual color of the coherent light source. The position of the second-order maximum, corresponding to two full wavelengths of path difference from the two slits, is most nearly 35.0cm. The position of the third-order minimum of intensity, corresponding to two and one-half wavelengths of path difference for rays arriving from the two slits, is most nearly 43.8cm. 1. Given that the two narrow slits in the barrier are separated by 10.0μm10.0μm and the distance between the barrier and the screen is 2.55 m, what is the wavelength, in nanometers, of the coherent light source used to create the interference pattern?  2. The student wishes to repeat the using different slit separations. What is the smallest slit separation, in micrometers, that produces a first-order maximum?  3. The student wishes to…

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=________

Interference fringes of the 1st order, created on the screen on one and the other side of the central axis in a double-slit experiment, are spaced 1.5 mm apart with a slit separation of 0.45 mm. The distance from the screen to the double-slit is 120 cm. Determine the wavelength of the light used.

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.
