Answer to: What are the different types of light microscopy, how do preparations for each differ, and what are the advantages or uses of each? By...
What wavelength of light (in nm) is absorbed when an electron in a hydrogen atom moves from n = 2 to n = 5? What wavelength of light is emitted from a hydrogen atom when an electron moves from the n = 4 energy level to the n = ...
The distance from the center of the lens to the focal point is the focal length of the lens. The focal point is on the opposite side of the lens to that from which the light rays originate.Convex lenses are used in things like telescopes and binoculars to bring distant light rays to a...
and the differing wavelengths make the different colors. Modern quantum theory says that particles of energy called photons make up light. The number of photons gives the brightness, and the energy in the photons creates its color. Both theories...
Light is a form of electromagnetic radiation that consists of components with different wavelengths. You might already know that visible light, i.e. the light that we actually see and perceive, is just a small portion of all the light there is. So, what if we could see all the...
multiplexing (WDM). AT&T's Bell Labs introduced this technique, which established a way to split a beam of light into different wavelengths that could travel through the fiber independent of one another. These optical networks are also calledphotonic networksbecause they use light to transmit data...
Well, plants are also capable of distinguishing between different wavelengths of light. Now, I don't want to confuse you. It is not like plants have eyes. Plants don't see in the sense that humans or animals do, but they do have photoreceptors.Photoreceptors are cells that respond to ...
Color has three dimensions: hue (e.g., purple), value (light/dark), and saturation (bright/dull) (Hanson, 2012). Color is actually a human perception of various wavelengths of light, and there are different kinds of light that can be used in interiors (natural/artificial; task/diffused;...
What is a photon of light? Why is wavelength the main limiting factor on limit of resolution in light microscopy? Why have most SETI searches been carried out at radio wavelengths? How to use a spectrophotometer to measure the absorbance of a solution at different wavelengths?
UltaViolet Light:Ultraviolet light is a part of the electromagnetic spectrum. Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. O...
