To solve the problem you must first know that by keeping the linear moment P1 = P2. You must find P1 from the system and equal it to P2 of the system, from that equation you clear the final velocity 1. Which will result in V1f = 60.16 cm / s to the north.I attach the solution.

Calculate the angle for the third-order maximum of 580-nm wavelength yellow light falling on double slits separated by 0.100 mm.
alekssr [168]

<u>Answer:</u> The angle of diffraction is 0.498°

<u>Explanation:</u>

To calculate the angle of diffraction, we use the equation given by Bragg, which is:

n\lambda =2d\sin \theta

where,  

n = order of diffraction = 3

\lambda = wavelength of the light = 580nm=5.80\times 10^{-7}m    (Conversion factor:  1m=10^{9}nm )

d = spacing between the crystal planes = 0.100 mm = 1.0\times 10^{-4}       (Conversion factor:  1 m = 1000 mm)

\theta = angle of diffraction = ?

Putting values in above equation:

3\times 5.80\times 10^{-7}=2\times 1.00\times 10^{-4}\sin \theta\\\\\sin \theta = 0.0087\\\\\theta=\sin ^{-1} (0.0087)=0.498

Hence, the angle of diffraction is 0.498°
