1. A viewing screen is separated from a double-slit source by 1.3 meter. The distance between the two slits is 0.020 mm. The second-order bright fringe (m = 2) is 2.5 cm from the center line. (a) Determine the wavelength of the light and (b) Calculate the distance between adjacent bright fringes​

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
