In a two-slit experiment using coherent light, the distance between the slits and the screen is 1.1 m, and the distance between the slits is 0.03 mm. If the second order bright fringe is measured to be 2.5 cm from the centerline on the screen, what is the wavelength of light in nanometers (nm)?

When measuring volume, why is it important to use the correct tools and units to attain the greatest accuracy? use specific examples from the lab to support your answer. (5 points)

The law of reflection states that the angle of reflection is equal to the angle of

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
