The speed is![v = 8.1 *10^{7} \ m/s](/tpl/images/0840/1860/1809b.png)
Explanation:
From the question we are told that
The real wavelength is![\lambda_r = 680 \ nm = 680 *10^{-9} \ m](/tpl/images/0840/1860/1a918.png)
The observed wavelength is![\lambda_o = 515 \ nm = 515 *10^{-9} \ m](/tpl/images/0840/1860/33590.png)
Generally the real wavelength of the stop light according to doppler effect is mathematically as
Here c is the speed of the light
and v is the speed of the physicist
So
=>![\frac{680nm}{515nm} = \sqrt{\frac{1 + \frac{v}{c} }{1 - \frac{v}{c} } }](/tpl/images/0840/1860/f0abe.png)
=>![[\frac{680nm}{515nm} ]^2= \frac{1 + \frac{v}{c} }{1 - \frac{v}{c} }](/tpl/images/0840/1860/ed636.png)
=>![1.743 = \frac{1 + \frac{v}{c} }{1 - \frac{v}{c} }](/tpl/images/0840/1860/b1c83.png)
=>![1.743 - 1.743\frac{v}{c} = 1 + \frac{v}{c}](/tpl/images/0840/1860/b80ea.png)
=>![0.743 = 2.743\frac{v}{c}](/tpl/images/0840/1860/183a9.png)
=>![v = \frac{0.743c}{2.743}](/tpl/images/0840/1860/b0eca.png)
=>![v = 0.2709c](/tpl/images/0840/1860/e0262.png)
substituting
for c
=>![v = 0.2709 * 3.0*10^{8}](/tpl/images/0840/1860/e73b3.png)
=>![v = 8.1 *10^{7} \ m/s](/tpl/images/0840/1860/1809b.png)
