The speed of the jet will be 340.0 m/sec. It is found as the ratio of speed of sound and the refractive index.
What is an index of refraction?
The refractive index of a substance also known as the refraction index or index of refraction is a dimensionless quantity that specifies how quickly light passes through it in optics.
The given data in the problem is;
c is the speed of light=340 m/sec
n is the index of refraction of air =1.00273
V is the speed of the jet
The index of refraction is found as;
[tex]\rm n = \frac{C}{v} \\\\ \rm v = \frac{334}{1.00273} \\\\ v=33.07 \ m/sec[/tex]
The speed of the jet will be 340.0 m/sec.
Hence, option D is correct.
