A beam of 443nm electromagnetic radiation is directed onto two slits that are 0.30mm apart, creating an interference pattern on a screen. If maxima #4 is 1.7cm from the central bright spot, how far are the slits from the screen?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
