Young's double slit experiment is one of the quintessential experiments in physics. the availability of low cost lasers in recent years allows us to perform the double slit experiment rather easily in class. your professor shines a green laser (564 nm) on a double slit with a separation of 0.108 mm. the diffraction pattern shines on the classroom wall 4.0 m away. calculate the fringe separation between the fourth order and central fringe.

Hi, your answer is not correct. this is a cumulative  

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
