the ocean floor begins
the steep slope down to the ocean floor
is the matter that energy can travel through such as air and water.
A luminous object
such as the sun, produces its own light.
the bending of light
objects transmit light energy.
transmit some light, but the light is scattered and the image is not clear.
materials do not allow light to pass through.

is to bend inwards and come together and converge.
It causes light rays to bend outwards and they diverge from each other.
