Light waves science

Wavelengths of light: Each hue in the visible spectrum has a corresponding wavelength measured in nanometers, which are only one billionth of a meter. Hue differences are tiny measurement differences between the crests of each wavelength. Red has the longest wavelength and violet the shortest.

Spectroscopy is the investigation and measurement of spectra produced by matter interacting with or emitting electromagnetic radiation.

Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes.

Are you teaching the properties of waves and looking for ideas to WOW your students? The characteristics of waves is one of the first things you teach in your

SCI INFO SHEET: Fundamentals of waves - Waves – such as light waves, sound waves, water waves, heat waves, radio waves and microwaves – are all around us. This article explains the fundamental characteristics of waves that help us understand their behaviour.

This simple light refraction experiment for kids is an awesome way to learn about the properties of light!
