PRACTICE ANOTHER
Light Emitting Diodes (LEDs) are semiconductor devices that emit light at specific wavelengths without emitting at any other wavelengths. LEDs can be used to create lasers
that are very compact since they are a solid state device. A pair of narrow, parallel slits separated by 0.262 mm are illuminated by the green LED laser (1 = 546.1 nm). The
interference pattern is observed on a screen 1.75 m from the plane of the parallel slits.
(a) Calculate the distance from the central maximum to the first bright region.
m
(b) What is the distance between the first and second dark fringes?
m
