Transmission through thin layers. In the figure, light is incident perpendicularly on a thin layer of material 2 that liesbetween (thicker) materials 1 and 3. (The rays are tilted only for clarity.) Part of the light ends up in material 3 as ray r3(the light does not reflect inside material 2) and r4 (the light reflects twice inside material 2). The waves of r3 and r4interfere, and here we consider the type of interference to be either maximum (max) or minimum (min). The table belowprovides the indexes of refraction n, n2, and n3, the type of interference, and the wavelength A in nanometers of the lightas measured in air.

A laser light source with wavelength λ = 545 nm is incident on a diffraction grating (as in the figure). The grating has 495 slits per mm. An observation screen is a distance L = 0.35 m from the grating. What is the separation between individual slits in the grating? Be careful with units: 1 nm = 10-9 m, 1 mm = 10-3 m, and 1 cm = 10-2 m. d = nm What is the distance y along the screen where the first-order diffraction peak is observed? y= cm source grating m=1
Source S is placed inside a glass water tank, as shown below. The surface of the water is covered with oil. Two monochromatic coherent light rays 1 and 2, go through the path as shown in the figure.

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=________
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.
