The various colors sometimes observed in clouds is another example of light being diffracted, this time by the clouds water droplets. This visual effect is a result of sunlight bending around the edge of the cloud. The visible effects of diffraction are most pronounced when the length of the opening through which the wave is passing is close to the light’s wavelength.Įxamples of light diffraction can be seen in nature every day! Take, for instance, a cloud’s ‘silver lining’. On the electromagnetic spectrum, the visible light spectrum falls between infrared and ultraviolet waves. This range is referred to as the visible light spectrum.

Electromagnetic radiation with a wavelength between 380 nm and 760 nm is visible to the human eye. The explanations for all three phenomena of light wave behavior are rooted in Huygen’s principle, which states that every point on a wavefront is a source of wavelets, which spread forward at the same speed.Īll electromagnetic waves are light, but only light from a certain section of the electromagnetic spectrum is visible to the human eye. Christiaan Huygens was a brilliant Dutch physicist, mathematician, inventor, and astronomer, known especially for his contributions to optics and mechanics. We’ll take you step-by-step through the basics and show you how you can do your own fun experiments and learn the science of diffraction. Light Diffraction is a complex topic, but at Rainbow Symphony, we take great pride in being a gateway to the joys of science for learners at all levels. However, this blog will focus on the wonders of diffraction of visible light waves. In fact, they can be observed for any wave, including sound waves, water waves, or any wave in the electromagnetic spectrum. These phenomena are not unique to visible light waves. For example, the direction change when a wave passes from water to air. Refraction is the change in direction a wave undergoes as it passes from one physical medium into another.Reflection occurs when a wave comes into contact with a surface, bounces off the surface, and is redirected back into its original medium.Diffraction is the phenomenon in which a wave changes direction as it bends around an object in its path or passes through an opening.They are either reflected, refracted, or diffracted. That is, the end of one medium and/or the beginning of another. Light waves are known to behave in one of three ways when they reach the boundary of a medium.
