Uncover the secrets of light waves and their impact on our world. Discover captivating experiments, mind-boggling facts, and practical applications that will leave you enlightened.
Seeing, hearing, feeling warmth, surfing, tuning the radio, using a cellphone – these and many more activities involve waves. But what is a wave? In this article, we get to grips with the different kinds of waves and look at the key characteristics of all waves – their wavelength, period, frequency, speed and amplitude. These concepts are important for describing waves of all kinds.
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.
In this post, we explore connections between the spectrum of visible light and the use of colours from the light spectrum to represent chakras, theorized to be the energy centres of our electromagn…

Before Isaac Newton, it was believed that white light was colorless, and that the prism itself produced the color. Newton's experiments demonstrated that all the colors already existed in the light in a heterogeneous fashion, and that particles of light were fanned out because particles with different colors traveled with different speeds through the prism. later that Young and Fresnel combined particle theory with wave theory to show that color is the visible manifestation of lights…
Learn about the dispersion of light, the electromagnetic spectrum, and how sunlight contains a range of wavelengths (photons of differing energy) with this video segment from Shedding Light on Science. Isaac Newton investigated sunlight by shining it through a glass prism; after the prism refracted the light, he saw a spectrum of colors. He recognized that sunlight was made up of many colors, which could not be further separated when passed through a second prism. Drops of water in the air…
