21) In the two-slit experiment, monochromatic light of frequency 5.00 x 1014 Hz passes through a pair of slits separated by 2.20 x 10-5 m. (c = 3.00 x 108 m/s) (a) At what angle away from the central bright spot does the third bright fringe past the central bright spot occur? (b) At what angle does the second dark fringe occur?

answer for a i) ii)

(c) A double slit experiment is performed with bluish green light of wavelength 512nm. The slits are 1.2mm apart and the screen is 5.4 m from the slits. (1) Calculate the angular position (0) of the third-order bright fringe in degrees. (ii) Find the width of the bright fringes as seen on the screen.

Light of wavelength 520 nm illuminates a slit of width 0.45 mm. (a) At what distance from the slit should a screen be placed if the first minimum in the diffraction pattern is to be 0.52 mm from the central maximum? 0.45 m 0.53 m 0.63 m 0.72 m (b) Calculate the width of the central maximum. 1.04 mm 2.08 mm 3.12 mm 4.16 mm

Monochromatic red light with a wavelength of 660nm is incident on a pair of narrow slits that are separated by a distance of 4.00×10^4 *m. A viewing screen is placed a distance of 120cm behind the slits to observe the intensity pattern of the light after passing through the slits. a) Relative to the center of the pattern, where is the center of the third bright fringe?

Problem 3: When laser light is passed through two narrow slits separated by 148 µm, an interference pattern is observed on a screen 1.67 m away. The distance between the central spot and the first-order constructive interference is found to be 5.3 mm. λ = Part (a) Find the wavelength of the laser light, in nanometers. || sin() cotan() atan() cosh() cos() asin() acotan() tanh() O Degrees Submit tan() acos() E ^^^ sinh() cotanh() Radians Hint () 7 BE * Feedback ∞52 63 1 8 9 4 5 + 0 END Vo BACKSPACE DEL CLEAR HOME I give up!

The coherence length of an ordinary white light source can be increased if we place a color filter in front of the source, so that the light that passes through the filter is somewhat monochromatic. The minimum wavelength of the emerging light is 546 nm. What is the maximum wavelength in order for the coherence length to be 0.1110 mm?
