Question

physics

To understand the assumptions made by the standard two-source interference equations and to be able to use them in a standard problem. For solving two-source interference problems, there exists a standard set of equations that give the conditions for constructive and destructive interference. These equations are usually derived in the context of Young's double slit experiment, though they may actually be applied to a large number of other situations. The underlying assumptions upon which these equations are based are that two sources of coherent, nearly monochromatic light are available, and that their Why are the two-source interference equations not valid for light from an incandescent bulb that shines onto a screen with a single slit, and then the light shines onto a screen with two slits in it and the light from the two slits finally shines onto a nearby screen? not monochromatic sources incoherent sources observed from a distance similar to or smaller than the separation between the sources 1 only 2 only 3 only 1 and 2 only 1 and 3 only 2 and 3 only all three Consider a road that runs parallel to the line connecting a pair of radio towers that transmit the same station (assume that their transmissions are synchronized), which has an AM frequency of 1000 kilohertz. If the road is 5 kilometers from the towers and the towers are separated by 400 meters, find the angle 0 to the first point of minimum signal (m = 0)- Hint: A frequency of 1000 kilohertz corresponds to a wavelength of 300 meters for radio waves. Express your answer in radians, to two significant figures.
