Answer 1

Answer #1

In double slit interference

d*sintheta = m*lambda

d = slit width = 1*10^-6 m

lambda = wavelength = 650 nm

10^-6*sintheta = 1*650*10^-9

theta = 40.54 degrees

Two narrow slits are used to produce a double-slit interference pattern with monochromatic light. The slits are separated by 7 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 21.5 mm...

In a Young's double-slit experiment, 586 -nm-wavelength light is sent through the slits

In a Young's double-slit experiment, 586 -nm-wavelength light is sent through the slits. A screen is held at a distance of 1.50 m from the slits. The second-order maxima appear at an angle of 2.50° from the central bright fringe. How far apart do the first-order (m=1) and second-order (m=2) maximum appear on the screen?

shows the fringes observed in a double-slit interference experiment when the two slits are illuminated by white light. The central maximum is white because all of the colors overlap. This is not true for the other fringes. The m = 1 fringe clearly shows bands of color, with red appearing farther from the center of the pattern, and blue closer. If the slits that create this pattern are 25 μm apart and are located 0.95 m from the screen, what...

Coherent light with wavelength lambda = 600nm passes through two very narrow slits and the interference pattern is observed on a screen at R = 3.00m from the slits. The first-order (m = 1) bright fringe is at 4.84 mm from the center of the central bright (m = 0) fringe. (a) How far apart (d) would the slits have to be? (b) Calculate the fring width (i.e. width of either bright or dark fring).
