Answer #1

here by using the formula

m = 2 * d / lambda

d = lambda * m / 2

d = 500 * 10^-9 * 1000 / 2

d = 0.25 mm

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,...

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...
