Why doesn’t the light from the two headlights of a distantcar produce an interference pattern?

Have seen some wrong answers by repeating the question which I don't want :(( Please don't answer like previous one You have been asked to predict the wave heights incident on the Fremantle railway bridge due to a wave train with offshore wave height of 1.15 m and period 14 s. The following information is given: (a) refraction analysis indicate that the spacing between the orthogonals is one half the deep water spacing. (b) water depth at the entrance to Fremantle harbour is 10m whilst at the Railway bridge it is 5 m. (c) width of river at the ocean entrance is 600 m and at the railway bridge is 100 m, respectively. [Neglect diffraction and frictional effects and approach the problem from energy considerations]

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.

Does the atmosphere as a whole stop visible light from reaching the Earth? (Hint: trace gases are a verysmall piece of the atmosphere).

When green (550 nm) light is shone through a double slit the angle of the first dark fringe is 1.9 degrees. Calculate the angle in degrees of the second dark fringe.
