Every element can only absorb certain wavelengths of light because of how the electrons are positioned around the nucleus. There is a fixed number of energy levels that each electron may move to, and each move will only occur if a specific amount of energy is absorbed. Thus each element, having differing electron orbital states can only absorb certain frequencies of light.

The element which has the ability to absorb the most heat energy is?
helium
Why don't white surfaces absorb as much light as black surfaces?
it's depends on element's of black surface that element absorb the sun light and convert it to thermal energy and in the other side white surface doesn't had a much element like black surface.
How many waves from a single ray of ultraviolet light with a frequency of 1.2x1015 Hz does your skin absorb during a one hour exposure?
a frequency of 1.2x10^15 Hz
What is the cooling element in the refrigerator?
The evaporation coils, where the HCFCs absorb heat and evaporate.
What is the emission of colored light rays during exposure to ulraviolet light?
Fluorescence. It happens when atoms' electrons absorb light at one frequency and emit at other (usually lower) frequencies. Sometimes two photons are absorbed by the same electron, and emitted as a single higher frequency, but this is not common.
What are selectivity barriers in communication?
The audience is not able to absorb all the information coming from a variety of sources; so the audience pick up information on selectively. The selectivity is affected by timing, context, and the degree of uniqueness of information
Which formal element does a viewer absorb first on viewing an artwork?
Which formal element does a viewer absorb first on viewing an artwork?
Which element is used to absorb heat in spacecrafts?
The element is used to absorb heat in a spacecraft is helium. There are modern technologies that are being developed for the same purpose.
What Element do coral animals absorb from ocean water?
calcium
The element which has the ability to absorb the most heat energy is?
helium
Why are certain colors absorbed into some objects but not others?
colors are different frequencies of light. atoms in objects vibrate in specific frequencies too. objects with atoms vibrating in the frequency corresponding to the color absorb that color and reflect the other frequencies they can't absorb. the color of an object is basically the frequency of light that it can't absorb.
What element is used to absorb heat in spacecrafts?
Beryllium (Be)
Why don't white surfaces absorb as much light as black surfaces?
it's depends on element's of black surface that element absorb the sun light and convert it to thermal energy and in the other side white surface doesn't had a much element like black surface.
Why intermediate frequency are constant?
The frequency spectrum has been distributed for various purposes. Otherwise, the people may use the frequencies of their choice & there will be wide range of interference. So, in order to ensure proper reception of signals, the standards have been fixed for the transmission of frequencies & also for the intermediate frequency because if the intermediate frequency is varied the overall frequency value will also vary. The intermediate frequency value should be so designed that it should not lie within the range of mixer stage. Otherwise, there is the production of noise signal due to the interference of mixer frequency & intermediate frequency. Also, the intermediate frequency should not be too high. Otherwise, it will reduce the selectivity of the receiver because of increase in bandwidth. Considering all these factors 455 khz is the most suitable intermediate frequency value for an AM receiver.

What is the frequency of a hydrogen atom?
An atom doesn't have a frequency. It can vibrate with many different frequencies. It can absorb radiation of different frequencies under different circumstances. For instance, electrons moving between various energy levels absorb and release characteristic frequencies of visible and ultra-violet light, and in a magnetic field radio frequency energy can be absorbed as the nucleus moves from one spin state to another. Bonds between hydrogen and other atoms absorb energies in the infra red. All these things give spectra of various frequencies, not an individual frequency.
