What else can I help you with?
Red light is low energy and has long wavelengths?
Actually, red light has relatively low energy compared to other colors in the visible spectrum, but it still falls within the range of visible light. It has longer wavelengths compared to colors like blue or violet, which have shorter wavelengths and higher energy.
Do x-rays have high or low frequency?
X-rays have high frequency. They have a wavelength shorter than ultraviolet light and a higher energy compared to visible light.
Does infrared high or low energy?
Infrared radiation has less energy (per photon) than visible light.
What color best attract heat and why?
Heat as radiation is best attracted to and held by dark colors, because they have low reflectivity. Stand in the sun on a hot summer day with a black shirt on, then with a white shirt on - the difference is immediately apparent.
How range of radiant energy arrange in order of energy or wavelength?
The range of radiant energy can be arranged in order of energy from high to low as follows: gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves. In terms of wavelength, the order would be reversed.
Red light is low energy and has long wavelengths?
Actually, red light has relatively low energy compared to other colors in the visible spectrum, but it still falls within the range of visible light. It has longer wavelengths compared to colors like blue or violet, which have shorter wavelengths and higher energy.
Does visible light have high or low energy?
Visible light has moderate energy compared to other forms of electromagnetic radiation. It falls within the range of wavelengths that are visible to the human eye, with shorter wavelengths of visible light corresponding to higher energy levels.
What happen to the light intensity when switch from low to high power?
The light intensity increases when you switch from low to high power, as more energy is being used to produce a brighter light.
Why is the light given off as fluorescence always of lower wavelength than the light absorbed?
It isn't. The usual way fluorescence works is indeed that a high energy light promotes an electron to a high energy state and it then cascades down through the energy levels giving off low energy quanta of light at each step. However there is the situation where low energy light input can act as an energy pump and promote an electron in a series of energy steps to a high energy state which it then releases in a single high energy drop emitting a quantum of light of a higher energy than the input.
Which colour has the shortest frequency?
Violet, Blue, Green, Yellow, Orange, Red The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. Thus gamma rays have the most energy, and radio waves have the least. Of visible light, violet has the most energy and red the least. Approximate frequency ranges for the various colors: Red 384 - 482 Orange 482 - 503 Yellow 503 - 520 Green 520 - 610 Blue 610 - 659 Violet 659- 769
Name two useful properties of coherent light?
High energy density. Low dispersion.
Why is a low energy light bulb described as more efficient than a normal light bulb?
Because efficiency is measured in Output/input. At the same light bulb output, one with lesser energy input required is higher in efficiency. Possible confusion come from description of low energy light bulb without stated the high or low energy is compared at what lux it can produce light.
How does the spectrum of white light from the sun?
The spectrum of white light from the sun includes all the colors of the rainbow, from violet to red. This is due to the sun's energy being emitted across a range of different wavelengths, with each color corresponding to a specific wavelength. When white light is dispersed, such as through a prism, its different wavelengths are separated, revealing the colors of the spectrum.
When electrons move from a high energy excited state to a low energy ground state. E Energy is absorbed by the atom?
No, energy is released by the atom when electrons move from a high energy excited state to a low energy ground state. This energy is emitted in the form of light or heat depending on the specific energy level transition. The difference in energy levels determines the wavelength of the light emitted.
What two colors make orange other than red and yellow?
There are two colors of light that, when mixed, produce the color orange. These two colors are high-intensity red and low-intensity green.
Do x-rays have high or low frequency?
X-rays have high frequency. They have a wavelength shorter than ultraviolet light and a higher energy compared to visible light.
What is the difference between high quality and low quality energy?
The main difference between high quality and low quality energy is in the perception. This will facilitate the proper grading of tasks with the high tasks using high energy and low tasks low energy.
