In a double-slit experiment the distance between slits is 4.4 mm and the slits are 0.97 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 460 nm, and the other due to light of wavelength 650 nm. What is the separation in meters on the screen between the m

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
