Laser light of an unknown wavelength falls incident on a pair of slits separated by 25.0 µm. This produces an interference pattern on a screen 1.80 m away with the first-order bright fringe being 39.7 mm from the center of the central maximum. What is the wavelength of the laser light?

Two narrow slits are used to produce a double-slit interference pattern with monochromatic light. The slits are separated by 8 mm, and the interference pattern is projected onto a screen 7 m away from the slits. The central bright fringe is at a certain spot on the screen. Using a ruler with one end placed at the central fringe, you move along the ruler passing by two more bright fringes and find that the next bright fringe is 23.5 mm...

Light of wavelength 532 nm illuminates a pair of slits separated by a distance of d= 0.42 mm. An interference pattern is observed on a screen placed a distance L away (L>>d). You may use the small angle approximation for this problem. What is the distance L if the width of the central bright spot of the interference pattern is delta(y) = 1.9 cm? The answer is supposed to be 15 m but i cant figure out how to get...

Two narrow slits are illuminated by a laser with a wavelength of 578 nm. The interference pattern on a screen located x = 4.50 m away shows that the third-order bright fringe is located y = 9.10 cm away from the central bright fringe. Calculate the distance between the two slits. First you have to calculate the angle of the maximum. Then you can use the formula for bright fringes of double slits. Incorrect.
