a. In a double-slit 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? b. Suppose you pass light from a He-Ne 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 B/10° relative to the incident beam. What is the wavelength of the light? c. What is the highest-order constructive interference possible with the system described in the preceding example? 4. a. State what is meant by monochromatic rays? b. Monochromatic light falling on two slits D/100 mm apart produces the fifth-order fringe at a A/5 angle. What is the wavelength of light in nanometers? c. Suppose a light with a wavelength of D x10 m passes a pair of slits with a separation of B x104 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?
