A hydrogen gas lamp emits a red wavelength at 656 nm and a violet wavelength at 434 nm. The light from the lamp is put through two slits. The slit separation is 0.120 mm, and the distance to the screen is 55.0 cm. What is the distance between the second red minima and the second minima?

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.
