Physics 2C Summer Session I Quiz #4 Multiple Choice. Choose the answer that best completes the statement or answers the question. 1. From the law of Malus S=S 0 = cos 2 Hence for four polarizers each of which has an angle of = ±= 8 we have S=S 0 = cos 2 = cos 2 ±= 8 ± 4 = : 531 ( A ) 30 : Hence the ray is rotated through 300 600 360 = 240 ( D ) : 3. The wavelength for a 6 : 40 ± 10 14 Hz spectral line is ² = c=f = 3 ± 10 8 = 6 : 40 ± 10 14 = 469 nm: The expression for the Doppler e/ect for light that is redshifted is ² obs = ² emit s 1 + v=c 1 v=c ! ² ² obs ² emit ³ 2 = 1 + v=c 1 v=c 1 + v c = ( ² obs emit ) 2 ´ 1 v c µ v c ´ ( ² obs emit ) 2 + 1 µ = ( ² obs emit ) 2 1 v c = ( ² obs emit ) 2 1 ( ² obs emit ) 2 + 1 = 1 : 308 1 1 : 308 + 1 v = : 308 2 : 308 c = +4 : 0 ± 10 7 m= sec ( C ) 4.
