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 ?
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?
Problem 22.65 Constants I Periodic Table Part A A Michelson interferometer operating at a 600 nm wavelength has a 3.92-cm-long glass cell in one arm. To begin, the air is pumped out of the cell and mirror M2 is adjusted to produce a bright spot at the center of the interference patten. Then a valve is opened and air is slowly admitted into the cell. The index of refraction of air at 1.00 atm pressure is 1.00028. How many bright-dark-bright...
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,...
1. An experimenter uses a Michelson Interferometer to measure one wavelength of blue light emitted by helium atoms. Mirror 2 is moved by computer until 15,000 new bright central spots have appeared. In total, it is moved by 3.3536 mm. What is the wavelength of the light?
Constants Periodic Table A Michelson interferometer operating at a 500 nm wavelength has a 2.26-cm-long glass cell in one arm. To begin, the air is pumped out of the cell and mirror M2 is adjusted to produce a bright spot at the center of the interference pattern. Then a valve is opened and air is slowly admitted into the cell. The index of refraction of air at 1.00 atm pressure is 1.00028 Part A How many bright-dark-bright fringe shifts are...
A Michelson interferometer operating at a 400 nmwavelength has a 2.31-cm-long glass cell in one arm. To begin, the air is pumped out of the cell and mirror M2 is adjusted to produce a bright spot at the center of the interference pattern. Then a valve is opened and air is slowly admitted into the cell. The index of refraction of air at 1.00 atm pressure is 1.00028. Part A How many bright-dark-bright fringe shifts are observed as the cell...
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?
