Hello,I need help with Q6.Thanks. DDDDDDD(b)Figure 6: Application of Huygen's Principle as a plane wave passes through a single slit. (a) Schematic of theprocess showing the change in direction of the wave as it passes through the slit. (b) Photograph of thediffraction of water. The lines labeled “D" indicate propagating lines of dark regions.Notice that in Figure 6, before passing through the slit, the wave was traveling to the right, but after it haspassed through the slit, the wave has spread out and is traveling in an array of directions. This spreading of awave when it is squeezed is the phenomena of diffraction.There are places to the right of the barrier where wavelets’ crests overlap other wavelets' troughs yieldingdestructive interference. Figure 6(b) shows the lines along which there exists destructive interference, theselines are labeled D.Q6. Directly onto Figure 6(b), label where you think the “lines" of constructive interference occur. Label one ofthese "C". (You may copy/paste this line segment:

An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.30 m apart are powered by a single-function generator producing sine waves at 1200-Hz frequency. A student walks along a line 12.5 m away and parallel to the line between the speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is (a) the wavelength of this sound and (b) the distance between the central maximum and the first maximum (loud) position along this line?
Two slits of width 2 m, each in an opaque material, are separated by a center-to-center distance of 6 m. A monochromatic light of wavelength 450 nm is incident on the double-slit.

Show that the distribution of intensity in a double-slit pattern is given by Equation 36.9. Begin by assuming that the total magnitude of the electric field at point P on the screen in Figure 36.4 is the superposition of two waves, with electric field magnitudes E1=E0sintE2=E0sin(t+) The phase angle in in E2 is due to the extra path length traveled by the lower beam in Figure 36.4. Recall from Equation 33.27 that the intensity of light is proportional to the square of the amplitude of the electric field. In addition, the apparent intensity of the pattern is the time-averaged intensity of the electromagnetic wave. You will need to evaluate the integral of the square of the sine function over one period. Refer to Figure 32.5 for an easy way to perform this evaluation. You will also need the trigonometric identity sinA+sinB=2sin(A+B2)cos(AB2)
