The wavelength of a monochromatic source is measured with a Michelson interferometer. An interference pattern is viewed on the screen. When the movable mirror moves d = 0.1 mm, 462 fringes move past a fixed point on the screen. What is the wavelength of the light in nm? A: 78 B: 104 C: 138 D: 184 E: 245 F: 325 G: 433 H: 576
5. You illuminate a Michelson interferometer with a helium-neon laser. The interference pattern is uniform - there are no stripes or rings. The laser has a wavelength of 632.8 nm. You move the mirror on the translation stage until the intensity of the interferometer output is maximum. You measure that the output intensity is 10 = 0.80 mW/cm . Then, you move the mirror on the translation stage by some additional amount Ar. You observe that the output intensity drops...
An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...
I need help with this Electromagnetic Waves homework (VIII.2) Michelson interferometer Consider a Michelson interferometer as shown in the figure. Two mirrors, MI and M2, are located at distances L and L2 L away from the center of the beam splitter. M has a slight misalignment angle 0 from the horizontal direction.

mirrors path 2 incoming light path 1 half-silvered mirror interference pattern 1. Shown above is a simplified diagram of a Michelson interferometer. Imagine placing a flat plate of transparent material in path 2 and rotating it slightly with respect to the beam. If the thickness of the plate is known to be d show that the rotated thickness is where 45 is the cos φ small angle of rotation. Using this change in the path length, find an expression for...
PHYSICS - GEOMETRIC PHYSICS - MICHELSON INTERFEROMETER From a textbook chapter entitled: "Interference" QUESTION: If one arm of a Michelson interferometer contains a tube 2.5 cm long that is first evacuated and then slowly filled with air (n=1.0003), how many fringes will cross the center? Assume light of 600 nm wavelength. Please highlight any relevant equations, and show a step-by-step worked out solution. Thanks
A Michelson interferometer is irradiated with light of wavelength 633 nm (He-Ne laser). When one of the mirrors is moved, 800 fringe pairs (each fringe pair is an adjacent dark and bright line) pass by a fixed point in the viewing pattern. How far was the mirrow moved?
Consider a Michelson Interferometer. A) Find the constructive interference criteria based on d_1 and d-2. B) If the light source has a 850nm constituent and the mirror is 0.9m from the screen, what would the distance y be to the first maxima if the path difference is 3 times 10^-2m? What is the intensity of the first peak if the amplitude of the electric field is 12.5MV/m?

An evacuated cell of length 10 cm is placed in one arm of a Michelson interferometer using a 589-nm light source. When methane gas is allowed to enter the cell, the interference pattern is observed to shift 75 fringes as the pressure increases to atmospheric value. Calculate the index of refraction of methane. If we remove the evacuated cell then, a shift of 50 fringes will correspond to displacing the movable mirror of the interferometer by what distance?
