Does Huygen's principle apply to water waves? Why do light waves bend when entering a different medium? Explain how to read a refractometer refractive index. Explain how to measure refractive index using a refractometer. What causes wave diffraction? How does a convex lens refract light? What i...
How does the visual environment affect proprioception? How does light pollution work? Why does white light turn into a rainbow when passing though a prism? Why is the rainbow different colors? Why does light refract? Describe the importance o...
Lenses serve to refract light at each boundary. As a ray of light enters the transparent material, it is refracted. As the same ray exits, it's refracted again. The net effect of the refraction at these two boundaries is that the light ray has changed directions. We take advantage of ...
How does hard water differ from soft water?Water as an Effective SolventMost substances dissolve in water; some dissolve better than others. Different mineral salts break down into ions and dissolve in water. Positively charged ions are called cations, and negatively charged ions are called anions...
A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light. Jeffrey Warren over at Public Labs created a tutorial showing how you can make your own...
A real diamond will refract light—this is what gives it sparkle and brilliance. To test your stone's reactivity, take a piece of paper and draw a small dot on it. Place the diamond over the dot and see if you can see the dot through the stone. If the diamond is real, then you ...
phenomenon called refraction. Light does not travel at the same speed through air and water, and when it moves between media of different densities, this causes a change in its direction. Within the stem, light refracts due to the boundary between air from the channels and water found in ...
But what does it really mean when we’re told that our vision is blurry because we have a refractive error? We see the world around us because of the way our eyes bend (refract) light. Refractive errors are optical imperfections that prevent the eye from properly focusing light, causing bl...
For instance, take the relationship between wood andlight. Wood, like all natural matter, reflects and refracts light. But just how much light it reflects and refracts depends on how the electromagnetic waves of the light interact with the particles -- like electrons -- that make up the ...
"Supermoon," where the moon was at perigee, which is the closest orbital point to the Earth while the moon was in full phase. This makes the moon appear larger by up to about 14% and brighter by up to around 30%. I went out and used my 5-inch refracting telescope to take ...
