At what angle in degrees is the first-order maximum for 465-nm wavelength blue light falling on double slits separated by 0.0540 mm?

Sodium vapor light averaging 589 nm in wavelength falls on a single slit of width 4.05 mm. The screen is 2.20 m away from a slit. a) At what angle in degrees does it produce a second minimum? b) What is the width of the central maximum? and What is the highest-order minimum produced?

In a double-slit interference experiment, the wavelength is 737 nm, the slit separation is 0.180 mm, and the screen is 33.0 cm away from the slits.  What is the linear distance between the sixth order maximum and the third order maximum on the screen in millimeters?

In a two-slit interference experiment, if light with wavelength 535.0 nm goes through two slits separated by a distance 0.244 mm and reaches a screen 1.17 m beyond the slits, how far apart will the interference fringes be on the screen? Answer in units of mm.

A single slit of width 4.50 x 10 ºm produces a first-order dark fringe at some angle. If the width of the slit is now changed to 3.08 × 10-ºm, a second-order dark fringe is found at three times the previous angle. What is the wavelength of the light?

A grating has 3800 slits per cm. It produces a second order bright fringe at a 22 degree angle. What wavelength of light is being used?

At what angle in degrees is the first-order maximum for 426 nm wavelength blue light falling on double slits separated by 0.045 mm?

Coherent light with wavelength 600 nm passes through two very narrow slits and the interference pattern is displayed on a screen 0.80 m from the slits. 13 bright fringes are observed with a spacing of 4.00 cm between the center of the outside fringes. What is the spacing between the two slits? (Give your answer in micrometers.) Ive submitted this question multiple times and it has been incorrect on every occasion. The answer is absolutely not 1.56mm.

At what angle in degrees is the first-order maximum for 450-nm wavelength blue light falling on double slits separated by 0.0480 mm?
