Visible light and colour makes up just a very small part of the Electromagnetic Spectrum. To make it a little easier to understand about light and waves of energy, the electro magnetic spectrum provides an illustrated method of showing the types of electromagnetic radiation in terms of wavelength and frequency, and how small a part visible light actually is in the whole spectrum. Visible light energy is made up of many frequencies and wavelengths and falls between Infrared and Ultra violet…

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also gain an understanding of the colors of the rainbow as the visible spectrum, each color corresponding to a different wavelength.

Electro-Magnetic Spectrum

Looking for tips on how to set up lighting for your indoor plants? Here are a few things to consider and some products that we recommend.

During this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications.

The electromagnetic spectrum is the name for the different forms of light that are given off by objects in the Universe. Radio waves, microwaves, infrared

Electromagnetic waves are composed of oscillating electric and magnetic fields. Know the formation, graphical representation, mathematical representation, intensity of electromagnetic radiation along with its speed in free space.
