A is a measured angle.
B is a unit of angular measurement.
Answer:
Length = 2.92 m
Diameter = 0.11 mm
Explanation:
We have 
, where:
is the length
We divide the first equation by the second equation to get:
Using this Area, we find the diameter of the wire:
To find the length, we multiply the two equations stated initially:
Galileo Galilei was the first scientist to perform experiments in order to test his ideas. He was also the first astronomer to systematically observe the skies with a telescope.

The basic difference is that the ordinary sources are incoherent that means that the discrete frequencies merge up to give an intermediate between the maximum and minimum frequencies. While the laser is coherent containing the single frequency with maximum amplitude. thus travelling far.
