Consider a Young's two-slit experiment in which the wavelength of light is 37% smaller than the distance between the slits. How many complete dark fringes would be seen on a distant screen? (Assume for all these questions that the screen is as large as it needs to be.)

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?

Why does lightning travel from clouds to the ground?

What is the single most important equation in all of physics?
