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 :)

1. Coherent light of wavelength 525 nm passes through two thin slits that are 0.0415 mm apart and falls on a screen 75.0 cm away. How far away from the central bright fringe on the screen is a.) the fifth bright fringe (not counting the central bright fringe) b.) the eighth dark fringe 2.

Light of wavelength 600 nm passes though two slits separated by 0.25mm and is observed on a screen 1.1m behind the slits. The location of the central maximum is marked on the screen and labeled y = 0. A very thin piece of glass is then placed in one slit. Because light travels slower in glass than in air, the wave passing through the glass is delayed by 5.0

Light from a red laser (650 nm) is incident on two slits separated by 0.5 mm. Each slit is 0.25 mm wide. Quantitatively sketch the pattern you would observe on a screen that is located 2.0 m from the slits. Your sketch should range from -10 mm to 10 mm and include only the fringes you would observe. (Label the locations of the fringes) PLEASE EXPLAIN THOROUGHLY!!!!

In Young’s experiment, monochromatic light of wavelength 600 nm shines on two slits separated by 0.3 mm, producing an interference pattern on a screen that is 2.0 m away. You put a thin sheet of glass (n = 1.5) at the top slit and you observe a dark fringe the central location of the screen. Furthermore, the fourth bright spot on both sides of the central location is missing. (a) Sketch the resulting interference pattern. Precisely state the spacing between...
