An element is selective in the frequency of light it will absorb This selectivity is due to its?
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.

What is the resonent frequency of oxygen?
The resonant frequency of oxygen typically refers to the frequency at which oxygen molecules absorb infrared radiation, which is around 60 terahertz. This absorption of infrared radiation is important for studying the atmosphere and climate.
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?
Your skin would absorb approximately 4.32x10^18 waves of ultraviolet light during a one-hour exposure. This can be calculated by multiplying the frequency of the light by the duration of exposure in seconds.
Does fiberglass absorb sound?
Fiberglass does absorb some sound, particularly high-frequency sounds. This is why it is commonly used as an acoustic insulation material in walls and ceilings to help reduce noise transmission. However, it may not be as effective at absorbing low-frequency sounds compared to other materials.
In order for a vibration to absorb infrared radiation it must?
In order for a vibration to absorb infrared radiation, it must be of a certain frequency that corresponds to the energy levels of the infrared light. When the frequency of the vibrational mode matches the energy of the incoming infrared photon, the molecule can absorb the energy and transition to a higher energy state. This leads to an increase in the molecule's vibrational energy, which manifests as an increase in temperature.
Do color filters absorb light?
Color filters selectively absorb certain wavelengths of light while transmitting others. The absorbed light energy is either reflected or converted into heat. This selective absorption is what gives color filters their characteristic color appearance.
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 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.
Do all molecules absorb electromagnetic radiation at some frequency?
No, not all molecules absorb electromagnetic radiation at a distinct frequency. The ability of a molecule to absorb radiation depends on its structure and the energy levels of its electrons. Molecules with specific functional groups or electronic configurations exhibit absorption at characteristic frequencies.
What Element do coral animals absorb from ocean water?
calcium
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 colors does magenta absorb?
Magenta primarily absorbs green light. It appears as a bright pinkish-red due to its selective absorption of green wavelengths.
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.

What element is used to absorb heat in spacecrafts?
Liquid ammonia is often used to absorb heat in spacecrafts. It has a high heat capacity and can efficiently absorb and transfer heat away from critical components.
What is the element used to absorb heat?
A common element used to absorb heat is water, as it has a high specific heat capacity and can absorb a large amount of heat energy without a significant increase in temperature. Other elements used for absorbing heat include certain metals like copper and aluminum due to their high thermal conductivity.
