Listen to a recorded reading of this page:.Take a ten question quiz about this page.If it has a lower amplitude, this is called destructive interference. If the resulting wave has a higher amplitude than the interfering waves, this is constructive interference. When the waves meet the resulting wave will have the amplitude of the sum of the two interfering waves.ĭepending on the phase of the waves the interference can be constructive or destructive. When one wave comes into contact with another wave this is called interference. As a result the white stripe will be less hot. ![]() A white stripe painted on the pavement will reflect more of the light and absorb less. The black pavement becomes hot from absorbing the light waves and little of the light is reflected making the pavement appear black. One example of absorption is black pavement which absorbs energy from light. This vibration absorbs or takes some of the energy away from the wave and less of the energy is reflected. In this picture the unpolarized light wave travels through the filter and then is polarized along a single plane.Ībsorption is when a wave comes into contact with a medium and causes the medium's molecules to vibrate and move. Longitudinal waves, such as sound, cannot be polarized because they always travel in the same direction of the wave. Station 2: Research (computer/tablet needed) Students will research properties of objects that reflect and refract light. Station 1: Assess Students will answer three real-world examples. Light waves are often polarized using a polarizing filter. Students will go through 7 stations reviewing reflection, refraction, absorption, and diffraction. Polarization is when a wave oscillates in one particular direction. ![]()
