In learning about the parts of a wave, students will learn about wavelength and use their understanding to observe how visible light can be measured. This standard emphasizes student understanding of ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens.

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...
