(a) Use the wave front representation to explain what happens to the amplitude of sound along a line equidistant from each source and perpendicular to the line connecting the sources. (b) Use a graphical representation (pressure-versus-position graph) to explain what happens along that line. (c) Which representation is more helpful? Explain.

(17) Please don't write on a paper. I can't understand handwritten.
A physics professor wants to perform a lecture demonstration of Young's double-slit experiment for her class using the 933-nm light from a He-Ne laser. Because the lecture hall is very large, the interference pattern will be projected on a wall that is 5.0 m from the slits. For easy viewing by all students in the class, the professor wants the distance between the m = 0 and m = 1 and maxima to be 35 cm. What slit separation is required in order to produce the desired interference pattern?
Consider soap bubble with very thin (or negligibly thin) area. These soap bubbles exhibit brilliant colors when exposed to sunlight. (credit: Scott Robinson). The index of refraction of soap is taken to be the same as that of water. A source a light produces for light with a wavelength of 490 nm.

Analysis of the reflected light shows that the wavelengths 360, 450, and 602 are the only missing wavelengths in or near the visible portion of the spectrum. That is, for those wavelengths, there is destructive interference. What is the thickness of the film? (Give your answer in nm.)arrow_forward8 In a double-slit experiment, the distance between slits is 0.50 mm and the slits are 2.0 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 480 nm, and the other due to light of wavelength 600 nm.
