What sort of interference is present in the bright areas of the graph? In the dark areas? Which properties in the experiment changed the spacing between the bright bands on the screen?

Would the pattern on the screen have changed if there had been three sources of light? Explain your answer.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
