A beam of coherent light of wavelength 623nm in air is
incident on a rectabgular block of glass with index of refraction
n= 1.40
A beam of coherent light of wavelength A0 623 nm in air is incident on a rectangular block of glass with index of refraction n 1.40. If, after emerging from the block, the wave that travels through the glass interfers destructively with the wave that travels through air. We ignore reflection on the block faces. Coherent...

In a double-slit interference experiment the slit separation is 8.40 x 10-6 m and the slits are 2.80 m from the screen. Each slit has a width of 1.20 x 10-6 m. a) An interference pattern is formed when light with a wavelength of 450 nm is shined on the slits. How far (in meters) from the center of the interference pattern on the screen do the third order (m = 3) bright fringes occur? (1.5 pts) b) If a...
