Problem 10: Consider the sodium doublet vapor lines, which have wavelengths of 589 nm (line a) and 589.6 nm (line b).   Randomized Variablesw = 2.15 μm L = 0.85 m   Part (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 2.15 μm.   Part (b) What is the distance in mm between these minima if the diffraction pattern falls on a screen 0.85 m from the slit?

a In the experiment of double-slit interference of microwaves, if the spacing of the uble slit is (3 cm) and the wavelength of the microwaves (2.5 cm), find the angles of the first and second maximums? b) In the experiment of Fabry-Perrot interferometer of microwaves, if the first distance between the two partial reflector was (di= 20.7 cm) and we moved the second partial reflector so the new distance between the partial reflectors is (d 40.2 cm) and we counted (13) minima's through this distance. Calculate the wavelength of the microwaves.

Mirror M, in the figure below is moved through a displacement AL. During this displacement, 240 fringe reversals (formation of successive dark or bright bands) are counted. The light being used has a wavelength of 634.8 nm. Calculate the displacement AL. 39.6 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. µm A single ray of light is split into two rays by mirror M, which is called a beam splitter. Light source The path difference between the two rays is varied with the adjustable mirror M1. M1 Telescope Mo As M1 is moved, an interference M2 pattern changes in the field of view. Need Help?

One and Two Slit Intensity Profile Two slits are d=7w apart, where w is the width of each slit. a) What are the angles of the first three bright spots (not including the center) of the substructure (due to two-slit interference)? Express your answer in terms of A and d. b) What are the intensities of light at the angles found in the previous part (considering both the envelope due to single slit diffraction and the substructure due to two-slit interference)? Express this in terms of Io, the intensity at 0 = 0. c) Extra credit: Are any bright spots in the substructure shadowed by the envelope? If so, which ones (not necessarily found in part a)).

An interferometer is an instrument that uses interference effects to makevery precise measurements of small changes in distance.Figure QB3a shows the set-up of a simple interferometer. The lightproduced by the laser (λ = 700 nm) travels to the beam splitter, C (a halfsilvered mirror), where 50% of the laser light travels straight throughwithout changing direction (beam 1) and the other 50% is reflected(beam 2).Beam 1 hits mirror A and returns to the beam splitter, where it is thenreflected towards the screen (D). Beam 2 hits mirror B and returns tothe beam splitter, where it then travels straight through without changingdirection, also reaching the screen.All parts of the interferometer are suitably enclosed such that the onlylight inside the device comes from the laser.(i) Assuming that AC and BC are the same length, explain what youwould expect to observe on the screen and why.(ii) The interferometer set-up is modified such that the length of BCis 0.000525 mm longer than the length…
