Light waves come in different wavelengths and frequencies. the color of the light we see is dependent on wavelength. when we see a rainbow, we are actually seeing

question 18 options:

light waves of the same frequency.

light waves of the same wavelength.

a single wave of light.

light waves of different wavelengths.

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.
