(2) diffraction of light passing through a narrow opening
Explanation:
As we know that when light passes through a small opening then the wavefront that passes through small opening will behave like a combination of large number of point sources.
Each point source will emit a wave and due to superposition of all such waves we can observe a pattern of maximum and minimum on the screen.
this is given by the equation
so here we can say that the correct answer will be
(2) diffraction of light passing through a narrow opening
The Starship Enterprise is powered by combining matter with antimatter. Suppose 1 kg of each are combined and ejected backward at the speed of light, what is the final speed of the Enterprise starting from rest? Assume that the mass of the Enterprise is 10,000 kg and the spaceship does not reach relativistic speed.
