, can alter waves in many different ways.
sound waves are an example of a mechanical wave. the origin of the energy source for a sound wave is a

this causes a sound wave that travels out from the source, carrying energy in all directions. the subsequent sound
waves need a media to travel through because the energy is transferred from particle to particle
light waves do not need a medium to travel through. in fact, the closer or denser the particle arrangement of a
substance, the slower the light wave travels. as light waves pass through different media, the light waves can speed up
or slow down. the change in the speed of the light waves causes

or the bending of light. the

of a medium is used to measure how much a light ray bends when it enters that medium.
medium wavelength vibration refractive index refraction simulation
wave absorption mass reflection

Explanation:

A wave is a repeating disturbance that transfers energy through matter or space. The state of matter is the medium. The origin of the energy source for a sound wave is a vibration. The change in the speed of the light waves causes refraction. The refractive index of a medium is used to measure how much a light ray bends when it enters that medium.

Answer:

A. wave, medium, vibration, refraction, refractive index
