In this activity, students will: READ an overview of light waves that covers their fundamental properties (amplitude, frequency, and wavelength) and where light fits in on the electromagnetic spectrum. The text also explores how light waves interact with materials through reflection, refraction, absorption, and transmission. DEFINE key terms.

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...

The worksheets will show students how to break apart the anatomy of wave and calculate the key measures that differentiate waves from each other. Students will explore the key vocabulary that is associated with light and sound waves.
Waves of Light. Overview: Most poisonous gases emitted from a volcano are colorless, so scientists rely on electromagnetic waves outside the visible spectrum to detect them. In this lesson, students learn about properties of the electromagnetic spectrum, including the wavelengths of visible light, ultraviolet energy, and infrared energy.
