Write down an expression for the width of the central bright line on a screen in the single slit diffraction experiment in terms of the diffraction slit (without the quotes) for products (e.g. width d, the distance from the slit to the screen D and the wavelength of light A. Consider D>> d. Please use "*" B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For exponents (e.g. A²) use A*A or A^2 notation: thus A³/B should appear as either A*A*A/B or A^3/B. For greek letters use "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acose use A* cos theta.

In a double slit experiment, the distance between the slits is 0.2 mm and the distance to the screen is 100 cm. What is the phase difference (in degrees) between the waves from the two slits arriving at a point 5 mm from the central maximum when the wavelength is 400 nm? (Convert your result so the angle is between 0 and 360°.)
Please show formula and units For the figure shown below, let R = 1.20 m and d = 0.120 mm and assume the slit system is illuminated with monochromatic 500 nm light. The first bright fringe (m = 1) happens at point P. Calculate the phase difference (ϕ) between the two wave fronts arriving to point P in radians when: a) θ = 0.500⸰ b) y = 5.00 mm. The value of θ in part b is not the same as the value of θ from part a. However, you may assume that θ in part b is small.

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. Consecutive bright bands on an interference pattern are 3.5 cm apart when the slide containing the slits is 10.0 m from the screen. The slit separation distance is 0.050 mm. y= ________ d=________ m=_______ L=________
Consider the sodium doublet vapor lines, which have wavelengths of 589 nm (line a) and 589.6 nm (line b). (a) Find the angle (in degrees) between the first minima for the two sodium vapor lines, when they fall upon a single slit with a width of 1.8 μm. (b) What is the distance in mm between these minima if the diffraction pattern falls on a screen 1.05 m from the slit?

In a Young's double slit experiment the wavelength of light is ?λ, separation between the slits is ?a and the distance to the screen is ?D. Give an expression for the interference fringe width ?w on screen if ?≫?D≫a. For Greek letters such as ?λ use the text equivalent - e.g. "lambda" (without the quotes, e.f. for ??Dλ use D*lambda).
Shown below is the central part of the interference pattern for a pure wavelength of red light projected onto a double slit. The pattern is actually a combination of singleand double-slit interference. Note that the bright spots are evenly spaced. Is this a double- or single-slit characteristic? Note that some of the bright spots are dim on either side of the center. Is this a single- or double-slit characteristic? Which is smaller, the slit width or the separation between slits? Explain your responses.

You just won a brand new laser pen and you want to know the wavelength of the light, so you set up Young’s double-slit experiment and observe the interference pattern on screen 1.2 meters away from the slits. The slits are 0.25 mm apart and you measure the distance between the centers of the first dark fringes on either side of the central maximum to be 3 mm. What is the wavelength of your new laser? If visible, what color should it appear, if not visible state the region of the EM spectrum? Hint: Draw a picture.
