Circle and correct the statements below that are false about diffraction. Justify your corrections. (a) Diffraction of light is evidence that we can treat light as a particle. (b) For single slit diffraction, constructive interference of light will present as dark spots on screen. (c) For single slit diffraction, as the wavelength of the light decreases, the diffraction pattern shrinks with all fringes getting narrower. (d) When λ/w is large in this scenario [λ >> w], there are little to no effects of diffraction observed. (e) All of the above statements are true.
The ship in the figure below travels along a straight line parallel to the shore and a distance d = 640 m from it. The ship's radio receives simultaneous signals of the same frequency from antennas A and B, separated by a distance L = 910 m apart. The signals interfere constructively at point C, which is equidistant from A and B. The signal goes through the first minimum at point D, which is directly outward from the shore from point B. Determine the wavelength of the radio waves. D
A hydrogen gas discharge lamp is used as a coherent light source illuminating NN slits in a barrier with a slit separation of 28 μmμm. The interference pattern is projected on a screen 2.00 m from the barrier. The first-order principal maxima to one side of the central maximum. The number of slits is sufficiently large that the individual lines are sharp and widely separated. Note that there are four different colors appearing in the source, violet is the color closest to the central maximum. λ=656λ=656 nm (red) λ=486λ=486 nm (cyan) λ=434λ=434 nm (blue-violet) λ=410λ=410 nm (violet) The blue-violet line is thin and somewhat faint, and it may be difficult to see without enlarging the figure. When viewing multiple orders of the interference pattern, the color sequence may change due to the interleaving of the different orders. 1. Using the values given in the problem statement, what is the distance along the screen, in centimeters, from the the central maximum to the first line? 2.…
