A 600 nm laser shines through a double slit in which the two slits are 0.8 mm apart, and each slit is 0.1 mm wide. Sketch what the pattern would look like on a screen 3 m away and indicate the central maximum. How many bright spots lie between the first single-slit minimums on either side? How far away is that first single-slit minimum from the center of the pattern? (you may assume the small angle approximations)

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...

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.

In Young's experiment a mixture of orange light (611 nm) and blue light (471 nm) shines on the double slit. The centers of the first-order bright blue fringes lie at the outer edges of a screen that is located 0.720 m away from the slits. However, the first-order bright orange fringes fall off the screen. By how much and in which direction (toward or away from the slits) should the screen be moved, so that the centers of the first-order...
