(A)In a double-slit experiment, it is observed that the distance between adjacent maxima on a remote screen is 10/20 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 10/100 mm and find that the third bright line on a screen is formed at an angle of 37/10 relative to the incident beam. What is the wavelength of light?

(C). What is the highest-order constructive interference possible with the system described in the preceding example?
