blue light puts off more energy when looking at the Electromagnetic spectrum as a whole from the right to left (or from highest wavelength and lowest frequency (i.e radio waves) all the way to gamma rays with extremely small wavelengths and high frequencies) the energy increases. so the energy of radio waves is much smaller than gamma rays now to put that to use in the problem of light, we know that red light has a larger wavelength (somewhere around 600-700 nm) and blue light with a smaller wavelength of somewhere around 475 nm thus the frequency (wavelengths per unit time) is larger for blue light using the equation E=((hc)/wavelength) where E is energy, C is the speed of light (3x10^8 meters/second) h= planks constant of 6.626 x 10^-34 joules x seconds we find that plugging in a smaller wavelength gives us a higher energy so blue puts off more energy hope that helps

How much does a light bulb change the temperature of a room?
Very little, but it is noticeable, with a bright light in a small room. A light bulb puts out between 9 watts (energy-saving fluorescent light bulb) to approximately 100 watts (bright incandescent light bulb). Your average bar-heater, for comparison, puts out about between 1200-2400 watts.
How much useful energy is in the output of a light bulb?
An ordinary incandescent light bulb puts out a good bit of light as well as a lot of heat - both useful forms of energy. Except that one uses a light bulb for the light. The heat is secondary and most often not desired. It can cause the room where used to be too warm and require more air conditioning to be cooled to be comfortable. Incandescent light bulbs can be rated as low as several milliwatts at low voltages to provide a small amount of light - as one would find on a radio dial from 50 to almost 100 years ago. They can also be several hundred watts, as would be use to light up a stadium. The energy out put in light of newer lights, such as compact florescent lights and LEDs are much better than incandescent bulbs and their heat output is much less - they're more efficient.
What is the energy transformation that takes place in a television?
Simple answer: Electrical energy comes in and heat, light and sound energy goes out. There are two input sources, the electromagnetic signal that is the actual information of what is to be displayed and there is also the electric power provided to operate the television. Typically, the power comes from an electrical cord plugged into the electrical outlet on the wall and the signal is a cable from an outside source or an antenna. The input energy is electrical energy to power the TV and the signal is electromagnetic energy. The output of primary interest is the image on the screen which is light energy, so the television puts out light energy which is also electromagnetic energy. The television may also produce sound, in which case there is sound energy put out. In the process of making light and sound, the components of the television heat, so heat energy is put out. Summary: Input: Electrical energy enters in two forms, electromagnetic signal and electricity. The electricity is the far greater source of energy. The energy in the signal is tiny. Output: Heat, light and sound exit the television. Heat is the largest and in excess of 90%. Sound energy will be substantially greater than the amount of energy contained in the light.
What is a machine that puts out as much energy as it takes in?
Such a fictional machine would be called a "Perpetual Motion Machine".
How many nuclear bombs would you have to detonate to equal how much energy the Sun puts out in one second?
One, if it had enough yield.
Which puts out the greater percentage of its energy as light an incandescent lamp or a mercury vapor lamp?
I would compare lamps of the same wattage to see which one puts out more lumens, which is the measurement of actual light output.
How does a laser work in a short sentence?
Examples are: A laser is a small light that puts atoms to their highest energy power.
What color do you get when you mix dark blue and light blue?
BLUE!!!!! ----- The color (hue) will be a blue, but it depends on how your mixing what color you finally get. If mixing subtractively (like inks on paper) your colors are filtering the light that reflects off the page (we'll assume the light and the page is white). In this case "light blue" is a transparent blue and dark blue is blue and black, so the white light in the room will be both filtered by the pale blue and the dark blue. The pale blue removes some of the light which isn't blue, the dark blue removes a lot of the light - even some blue. None of this puts any light back, so the dark blue would dominate - you would get dark blue. If you were mixing light (additive mixing), dark blue is just a small amount of (dim) blue light and light blue is blue light with a bit less of all other colours in it (white). What you get then is the light blue, with just a little extra blue in it. Imagine a room in daylight and switching on a blue light-blub - would you notice the room becoming more "blue"? You'd probably still call it light-blue. If mixing opaque paints and you took a pale blue (blue+white) and very dull blue (blue+black) you would get a cool-blue-gray. You certainly wouldn't get back to a spectrum (saturated) blue.
What is the average energy energy consumption of an energy saving light bulb?
Fluorescent lighting is much more energy efficient than incandescent lamps, usually by as much as 60 to 80%. That also translates into a corresponding energy savings. I don't recall the exact figure off hand, but the light output from a fluorescent lamp is about three times it's rating. For instance, a 40 watt fluorescent puts out the equivalent light of a 120 watt incandescent bulb.
What happen when an atom has more electrons that can fit in one energy level?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.

A light bulb converts 10 percent of the electrical energy and thermal energy it uses into radiant energymake a hypothesys about the other form of energy produced?
A lightbulb usually won't use thermal energy, only electrical energy. By conservation of energy, if 10% of the electrical energy is converted into radiant energy, the remainder is wasted - basically as heat.
When an atom has one or more electrons in higher energy levels?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
Are Jessie j's lips blue?
Not naturally, no. They are only blue when she puts on lipstick.
The measure of a stars brightness is called its what?
Scientists actually use two measurements to identify a star's brightness. One is luminosity, or the energy that star puts out. Another is magnitude, or the amount of light a star puts out.
What kind of energy is given off by an atom bomb?
An atomic bomb puts out many kinds of energy: Heat Light Radio waves Electrical And as these energies move outward, they in turn trigger many other types of energy.
Why is energy needed in catabolism?
technically yes, but the energy that the reaction puts out is greater than the energy put in.
