Would the headlights of a distant car form a two-source interference pattern? If so, how might it be reserved? If not, why not?
(a) The transmitters emit identical signals in phase with each other, which the driver receives on the car radio. When the car is at point A, 1 = 440 m and 2 = 171 m away from the transmitters, the radio picks up a maximum net signal. What is the longest possible wavelength of the radio waves?
(b) How long after the car passes point A does the radio experience a minimum in the net signal? Assume that the wavelength has the same value as in the previous problem.
The distance between the two luminous lines was measured as 0.5 mm in the interference pattern formed by 5890 a reflected from the oil layer with refractive index n=1.45, decaying perpendicular to the surface of the water. Since the refractive index of water is 1.33, what is the thickness of the oil layer?

The width of each slit is a, and the distance between the centers of the slits is d = 9.00 mm.

- The thickness of oil spill can be measured by microwave reflection. A drone directs microwave beam from above. The two oil surfaces reflect microwave back to the drone. The refractive index is 1.5 for crude oil, and 1.34 for sea water. At one spot, the strongest reflected frequency (zeroth order interference) is 6 GHz. The oil is _____ mm thick.arrow_forwardAn 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?arrow_forwardWhy is the following situation impossible? Two narrow slits are separated by 8.00 mm in a piece of metal. A beam of microwaves strikes the metal perpendicularly, passes through the two slits, and then proceeds toward a wall some distance away. You know that the wavelength of the radiationis 1.00 cm ±5%, but you wish to measure it more precisely. Moving a microwave detector along the wall to study the interference pattern, you measure the position of the m = 1 bright fringe, which leads to a successful measurement of the wavelength of the radiation.arrow_forward
