Question | Answer |
---|---|
The bending of waves as they pass into a different medium | refraction |
energy emitted in the form of EM waves | radiation |
the release of energy by particles of matter that have absorbed extra energy | scattering |
the material that gives paint its color by absorbing some colors of light and reflecting others | pigment |
occurs when waves overlap and combine | interference |
the entire range of EM waves such as light, radio waves, microwaves and x rays | electromagnetic spectrum |
the bending of waves around a barrier or through an opening | diffraction |
the passing of light through matter | transmission |
materials that transmit light easily, without scattering | transparent (absorption) |
waves that are used in radars | microwaves |
can be created by combining red, green, and blue light | white light |
the transfer of energy from light waves to particles of matter | absorption |
when a wave bounces off an object | reflection |
materials that do not transmit any light | opaque |
materials that transmit and scatter light | translucent |
