In a doubleslit experiment, it is observed that the distance between adjacent maxima on a remote screen is D/20 cm. What happens to the distance between adjacent maxima when the slit separation is double? (25 points) b. Suppose you pass light from a HeNe laser through two slits separated by D/ 100 mm and find that the third bright line on a screen is formed at an angle of 3/10 0 relative to the incident beam. What is the wavelength of the light? (25 points) 0. What is the highest-order constructive interference possible with the system described in the preceding example?

Monochromatic light falling on two slits D/lOO mm apart produces the fifth-order fringe at a D/S angle. What is the wavelength of light in nanometers? c. Suppose a light with a wavelength ofD x10'6m passes a pair of slits with a separation ofB x10'4 m. Determine the angle which corresponds to the first bright fringe. d. Blue light (wavelength 400nm) is sent through a double slit. The slits are D/ 10 nm apart. The light then hits a screen which is B cm behind the double slit. How far is the first bright fringe from the second bright fringe? PHY 156
