A 750 nm red light is not reflected in air by a thin film deposited on glass. If the thickness of the film is 150 nm and glass has a refractive index of 1.44, what is a possible value of the index of refraction of the thin film? 1.15 1.25 1.40 1.20
Parallel rays of monochromatic light with wavelength 575 nm illuminate two identical slits and produce an interference pattern on a screen that is 75.0 cm from the slits. The centers of the slits are 0.640 mm apart and the width of each slit is 0.434 mm. If the intensity at the center of the central maximum is 4.20×10−4 W/m2, what is the intensity at a point on the screen that is 0.850 mm from the center of the central maximum?
