Light with a wavelength of 612 nm in air travels at 1.92 x 108 m/s in a particular type of glass. the index of refraction for water is nwater= 1.33 (a) determine the index of refraction for the glass. (b) determine the wavelength in the glass. (c) determine the critical angle for the glass/air boundary. (d) determine the critical angle for the glass/water boundary.

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.
