a. In a doubleslit experiment, it is observed that the distance between adjacent maxima on a remote screen is %/20 cm. What happens to the distance between adjacent maxima when the slit separation is double? b. Suppose you pass light from a He-Ne laser through two slits separated by 8/ 100 mm and nd that the third bright line on a screen is formed at an angle of 53/ 10 0 relative to the incident beam. What is the wavelength of the light? c. What is the highestorder constructive interference possible with the system described in the preceding example? 2. a. State what is meant by monochromatic rays? b. Monochromatic light falling on two slitsfi / 100 mm apart produces the fthorder fringe at a 2/ 5 angle. What is the wavelength of light in nanometers? c. Suppose a light with a wavelength of 8 x10'6m passes a pair of slits with a separation of 53x10'4 m. Determine the angle which corresponds to the rst bright fringe. (1. Blue light (wavelength 400nm) is sent through a double slit. The slits are 8/ 10 nm apart. The light then hits a screen which is 55 cm behind the dOuble slit. How far is the rst bright fringe from the second bright fringe
