please help answer

A single slit forms a diffraction pattern with monochromatic light. The third minimum of the pattern occurs at an angle of 22 from the central maximum. The angle at which the sixth minimum of the pattern occurs is closest to: 487 52 899 11.2 Question 10 1 pts In a two-slit experiment, a second-order bright fringe is located at an angle of 73 away from the centerline. If the wavelength of light is 630 nm, how far apart are the two slits? 2.9 um 1.5 pm 13.2 um 7.1 um In a two-slit experiment. monochromatic coherent light of wavelength 400 nm passes through a pair of slits separated by 1.3 x 10'5rn At what angle away from the centertine does the first bright fringe. or maximum. occur? 334 119 23.20 SL6" Question 2 1 pts In a twoslit experiment. the slit separation is 2.5 x 10'5 m. The interference pattern is created on a screen that is 1.65 m away from the slits. If the 4th bright fringe on the screen is 3 cm away from the central fringe. what is the wavelength of the light? 303 nm 552 nm 623 nm 11? nm Treat each of your eyes as a circular aperture of diameter 1.2 mm. Light of wavelength 600 nm is used to View two point sources that are 1000 m distant from you. How far apart must these two point sources be ifthey are to bejust resolved by your eye? 4? cm 28 cm 61 cm 5cm Question 4 1 pts A 24 mm wide diffraction grating has rulings of 600 lines per mm. Light is incident normally to the grating. The longest wavelength that forms an intensity minimum in the third order is closest to: 3.34 x 10" m 3.43 x ll'J'4 m 1.1? x 10\" m 632 x 10-4 m Two radio antennas are 300 m apart on a north-south line. The two antennas radiate in phase at a frequency of 3.1 MHz. All radio measurements are made far from the antennas. The smallest angle (excluding the central maximum]. measured north of east from the antennas. at which destructive interference of the two radio waves occurs. is closest to: 621 35.9\" 183 12 Question 6 1 pts A diffraction grating has 450 lines per mm. What is the highest order maximum that contains the entire visible spectrum from 400 nm to 1'00 nm? 5 Y 2 9 A diffraction grating has 200 lines per mm. If light of fretwencyr 3x 1015 Hz is sent through this grating, at what angle does the rst order maximum occur? 10.42 115 421 633 Question 8 1 pts Coherent light of wavelength 500 nm passes through a pair of thin slits that are 2.6 X 10'5 rn apartr At what angle astray.f from the centerline does the second bright fringe occur? 8.9\" 7-6.1\" 1 13 0.35'1
