If you jump in first, submerge yourself in the water, and look up at your friend still standing at the edge of the pool, the red color of his trunks will appear the same as they did before you jumped into the pool. The color always is dependent upon the light's frequency, which is the number of waves of the light that pass a given plane in space per second (that is, the number of cycles per second). Tooth color is determined by the paths of light inside the tooth and absorption along these paths. But the frequency remains the same, and so does the color. A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. The same circumstances would be true if this were a huge container of water with glass on all four sides. Chlorophyll gives plants their green color. Color is determined Also, if a ray of colored light, say red, were to pass from air into glass, theoretically, would the color change while inside the glass? It is determined chromatically by pigment con- tent (measured by hue and chroma) and achromatically by scattering of light by the microstructure (measured by lightness), the latter of which has received mini- A. diffracts. • 1. Although the color of light emitted from a semiconductor die is determined by the combination of chip materials, and the manner in which they are assembled, certain optical characteristics of the LED can be controlled by other variables in the chip packaging. Wiki User Answered 2015-12-08 23:26:04. change of photons. Finally, if you immerse yourself entirely in the water, you will perceive no variation in the red color of the trunks. Our perception of color is not an objective measure of anything about the light that enters our eyes, but it correlates pretty well with objective reality. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Digital Image Processing (DIP) Objective type Questions and Answers. In two of the cases, when the red light is passing from air into water or water into the air, the wavelength changes, but the frequency of the red light remains the same.

That the color of any light is determined by the output of the three cone systems in our retinae is known as the: a. Light is made up of wavelengths of light and each wavelength is a particular color. Color is a function of the human visual system, and is not an intrinsic property. The actual skin color of different humans is affected by many substances, although the single most important substance is the pigment melanin.Melanin is produced within the skin in cells called melanocytes and it is the main determinant of the skin color of darker-skin humans. The two main types of LEDs presently used for lighting systems are aluminum gallium indium phosphide (AlGaInP, sometimes rearranged as AlInGaP) alloys for red, orange and yellow LEDs; and indium gallium nitride (InGaN) alloys for green, blue and white LEDs. Answered By. Upvote (0) Was this answer helpful? However, the color will remain the same because the frequency of that color of light remains the same from one medium to another. Moonlight leans toward red, but we perceive it as blue. Let's say that red laser light is aimed at a slab of dense crown glass with an index of refraction of 1.60.

For instance, if you observe a beach ball sitting near the edge of a swimming pool, then jump into the swimming pool and look up at the beach ball while your head is submerged under water, all the colors on the beach ball will appear the same as they did when you were standing in the air. Objects don't have a color, they give off light that appears to bea color. The beam of light will be the same shade of red both outside and inside of the glass. The color of light is determined by ____ of the light waves. dependent upon the light's frequency, which is the number of waves of the light that pass a given plane in space per second Question. Cloudflare Ray ID: 645674a2cdb51f19 If you were submerged in the water, and the red laser light were shining into one side, then passing through the glass and the water and into your eyes, it would appear as red to you as if you were outside of the container and looking at the same laser light in the air. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws. Author has 70 answers and 102.5K answer views The convention is to refer to wavelength (when light travels in a vacuum (or in air which is close enough)); however, color probably depends on frequency, which is independent of the medium traveled (Boynton 1979, p 64). See Answer. Place the straw on the other side of the glass of water and view it through the water and the glass; the color will not change. Black and white are not generally considered true colors; black is said to result from the absence of color, and white from the presence of all colors mixed together. A simple way to test to see if the red color of an object appears the same in different media is to fill a glass with water and get a red straw. Top Answer. But this is true only if the light is traveling through only one medium, such as air. a. the medium c. the frequency b. the speed d. the amplitude The color of light is determined by THE FREQUENCY of the light waves.
