1. What is the separation between two slits for which 643 nm orange light has its first maximum at an angle of 32.4º? Give your answer in microns.
2. The headlights of a car are 1.2 m apart. What is the maximum distance in kilometers at which the eye can resolve these two headlights? Take the pupil diameter to be 0.39 cm. Use light of wavelength 578 nm to calculate the answer.
3. What is the distance between fringes (in millimeters) produced by a diffraction grating having 119 lines per centimeter for 693 nm light, if the screen is 1.96 m away?
Plz answer all questions, will give thumbs up in appreciation :)
we know for double slit interference the condition for m-th order interference maximum is given by
