Abstract

Interferometer Michelson method has been used to measure wavelength of dioda laser, refractive index of glass and air . Interferometer beforehand calibrated by source of He-Ne laser then determined dioda laser wavelength by shifting movable mirror . index refractive of glass determined with variation angle inclination of glass, and index refractive of air obtained with pressure variation every increase 10kPa at cell vacuum Result of measurement for the wavelength of red dioda laser l = (660.5±1.6)nm and green dioda laser l = (530.5 ± 2.7) nm . For the measurement of index refractive of glass used glass with thickness 5.64 mm and obtained result (1.49 ± 0.06 ) when used He-Ne laser and (1.52 ± 0.01)when used green dioda laser. At determinate index refractive of air, appear change linear for index refractive air cause change pressure 5 n 1 0.2166x10 p − = + .
