light: a range of energy waves
light waves traverse in straight lines until they strike a surface. when light waves strike a surface, three things can happen. the light waves may be absorbed by the surface, bounce off the surface, or pass through the surface. the bouncing of light waves off of an object is reflection.
these objects are seen when the reflected light waves strike someones eyes. a mirror is an example of this. refraction is the bending of light, and takes place when light waves travel through two different transparent materials. observing a straw in a glass of water appearing to bend would be described as refraction, or the bending of those energy waves.
the range of energy waves that includes all visible and invisible light waves is called the electromagnetic spectrum. waves in the electromagnetic spectrum are arranged by the amount of energy they have.
gamma waves are extremely powerful, and have the most energy of all the waves in the electromagnetic spectrum. they are used to fight types of cancer. another type of wave is x - rays. these easily pass through skin, but not bones. ultraviolet waves are
which of these is the best summary for the selection?
select one:
humans cant see all light waves, but insects and animals can.
light waves are used to fight cancer.
light waves can be absorbed by a surface, bounce off a surface, or pass through a surface.
there are different kinds of light waves and they each have different types of energy.

Explanation:

The passage mainly describes the behavior of light waves (reflection, refraction) when they strike a surface and also mentions different types of waves in the electromagnetic spectrum like gamma - rays, X - rays, and their properties and uses. The best summary should cover the main aspects of light wave behavior and the electromagnetic spectrum. Option C correctly summarizes that light waves can be absorbed, bounce off, or pass through a surface.

Answer:

C. Light waves can be absorbed by a surface, bounce off a surface, or pass through a surface.
