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,...
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?
A Michelson interferometer is illuminated with 500 nm light. One of the mirrors is moved so that 1000 fringes move past the crosshairs of the observing telescope. How much has the mirror moved?
A Michelson interferometer is illuminated with 500 nm light. One of the mirrors is moved so that 1000 fringes move past the crosshairs of the observing telescope. How much has the mirror moved? (Note the useful YouTube video)How could you use an interferometer to tell if the wall of a liquid storage tank buckles by a small amount when the tank is filled?
Moving mirror M2 of a Michelson interferometer a distance of 120 μm causes 470 bright-dark-bright fringe shifts. What is the wavelength of the light? Answer in nm.
A Michelson interferometer uses red light with a wavelength of 656.45 nm from a hydrogen discharge lamp. How many bright-dark-bright fringe shifts are observed if mirror M2 is moved 1.7000 cm ?
-/5 POINTS KATZPSE1 36.P.045. MY NOTES ASK YOUR TEACHER Michelson's interferometer played an important role in improving our understanding of light, and it has many practical uses today. For example, it may be used to measure distances precisely. Suppose the mirror labeled 1 in the figure below is movable. -L Light source Detector If the laser light has a wavelength of 694.0 nm, how many fringes will pass across the detector if mirror 1 is moved just 1.860 mm? fringes...
You are using a hydrogen discharge tube and high quality red and blue light filters as the light source for a Michelson interferometer. The hydrogen discharge tube provides light of several different wavelengths (colors) in the visible range. The red light in the hydrogen spectrum has a wavelength of 656.3 nm and the blue light has a wavelength of 434.0 nm. When using the discharge tube and the red filter as the light source, you view a bright red spot...

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...
