WHAT IS WAVE REFLECTION, ABSORPTION & TRANSMITTANCE?

A wave is a repeating pattern of motion that transfers energy from place to place. When waves come in contact with an object, a few things can happen. The wave can be transmitted, which means to pass through the object. It can be absorbed, in which the wave is converted to thermal energy, or it can be reflected (sent off in a new direction).

LET’S BREAK IT DOWN!

Waves have properties.

Waves have properties.

A wave is a repeating pattern of motion that transfers energy from place to place. All waves have properties such as amplitude, wavelength, and frequency. These properties can be used to describe the wave. The amplitude of a wave determines how loud a sound is and how bright light is. Wavelength is the length of one wave. Frequency is how many waves occur in 1 second. The wavelength and frequency of a light wave determine color. A light wave is measured in nanometers. Different wavelengths produce different colors. Higher wavelengths produce brighter colors such as red, and lower wavelengths produce darker colors such as violet.
