In an interference pattern formed bv two coherent sources, the maximum and minimum intensities are 91, and I, respectively. The intensities of the individual wave are (a) 31, and I, (b) 41, and I, (c) 51, and 41, (d) 91, and I,

An interference filter has a dielectric layer (refractive index 1.34) with a thickness of 0.805 μm. If the determination is to be based on the first-order interference, calculate the wavelength (nm) can be transmitted?

Consider two identical antennas separated by 9.00 m that radiate in phase at 120 MHz. A receiver placed 150 m from both antennas measures an intensity Io. The receiver is moved so that it is 1.8 m closer to one antenna than to the other.

Monochromatic coherent light of amplitude E, and angular frequency w passes through three parallel slits, each sepa- rated by a distance d from its neighbor. (a) Show that the time-averaged intensity as a function of the angle 0 is I(0) = I (2nd sin e 1+ 2 cos max (b) Explain how this expression describes both the primary and the secondary maxima. (c) Determine the ratio of the intensities of the primary and secondary maxima. Hint: See Problem 16.
