Fullform of APPLE -geostationary satellite?
The fullform of APPLE stands for: Ariane Passenger Payload Experiment.
Jobs that end with ir are fair and funfair. Another job that might be described with the ending of ir is someone who can repair. Examples are appliance repair or automotive repair.
Why do different elements emit different colors when they are heated?
because when elements are heated there electrons become excited and jump through the elements "steps" and as they become less excited the jump back down steps emitting a unique wavelength and the visible wavelength is the colour we see
--------------------------------------
The wavelength of the spectral lines emitted by different elements are specific for each element. Consequently the colour is also different.
Can both Rutherford and Bohrs model of the atom explain spectra lines of elements?
No, Rutherford's model of the atom fails to explain the discrete spectral lines of elements. Bohr's model, which incorporates quantized energy levels and electrons moving in well-defined orbits, successfully explains the spectral lines of elements by linking them to the transitions between electron energy levels.
How do you calculate frequency in ir spectroscopy?
In IR spectroscopy, the frequency of a vibration is related to the wavenumber, which is measured in reciprocal centimeters (cm^-1). The frequency can be calculated using the equation: frequency (Hz) = wavenumber (cm^-1) x speed of light (cm/s).
The chemical composition of a star can best be determined by?
Analyzing its a light with spectroscopy
Why are the lines in the line spectrum of an atom of fixed wavelength and frequency?
The lines in the line spectrum of an atom are fixed because they correspond to specific energy levels in the atom. When an electron transitions between energy levels, it emits or absorbs energy in the form of photons with specific wavelengths and frequencies, creating distinct lines in the spectrum. These lines are fixed because the energy differences between the energy levels are constant for a given atom.
Why ping pong ball rolls in air for longer time?
A ping pong ball rolls for a longer time in air due to its low mass and high surface area, which results in less air resistance compared to heavier or more aerodynamic objects. This lower air resistance allows the ball to maintain its speed and momentum for a longer period before coming to a stop.
Which of these means is most and least use to generate electricity pictures?
There are no items on that list that are used to generate electricity pictures.
What are 5 methods of analysis in chemistry?
How is UV spectroscopy generally used?
Its used to separate and or transition chemicals from one state to another, identify chemicals, verify chemical naturals, transition different metals ions, metal atoms, and other high intense chemicals.
What is laser spectroscopy the study of?
Laser spectroscopy studies the effects of lasers on molecules. The main purpose of laser spectroscopy is to learn more about the reactions of molecules to light, and how this can aid in development of light-sensitive technology.
No, light is not two dimensional. Light is an electromagnetic wave that propagates in all directions in a three-dimensional space, carrying energy and information. It can travel in a straight line or be refracted, diffracted, or reflected in different directions.
Can photons of light be seen with the naked eye?
Since photons are the basic unit of electromagnetic radiation, and since visible light is electromagnetic radiation, yes, photons within the visible light spectrum can be seen with the naked eye.
How do you determine wavelength of source in diffraction grating?
In diffraction grating we use the expression N m L = sin @
Here N is the number of line per meter length in the gartin. m the order (1,2,3) L- lambda which stands for the wavelength of monochromatic light used to perform experiment
And @ is the angle of diffraction for which we get maximum
What is UV-VIS-IR transmission spectra?
It is a spectra that shows how transparent a material can be. in scientific terms, it is incidence of electromagnetic radiation (from the UV, Visible, Infrared wavelength regions) from a source to a material, and there is a detector which records the amount of radiation remaining after the transmission (these radiation that is gone is either reflected of the surface or absorbed by the material). The equipment that measures this is called UV-Vis-NIR spectrometer.
Chemical interference occurs due to the absorbance/emission by molecules that did not break down into atoms. Inductively-coupled plasma mass spectrometry has less chemical interference as its hotter temperature breaks down everything into atoms.
Spectrographs are instruments that separate EM radiation (primarily light) into a spectrum of frequencies and record the data. The intensity of radiation at the different frequencies can be used to ascertain information about the source of the radiation or the material through which it is passing.
Why the mull technique is used in IR Spectroscopy?
Mull technique is the only technique which can be used for Ethacrynic acid. silicon oil is used to grind sample and in it. irt is placed on sodiun cells and cells are overlapped and kept in holder in FTIR apparatus.
Is the spectrum of an element limited to the visible region of the electromagnetic spectrum?
No. The emission and absorption spectrum covers everything from UHF radio to X-rays.
(There are no energy level transitions that correspond to the low energy HF or VHF
radio bands and below. The lowest-energy transition is the one at 1420 MHz/21 cm.)
Why an exssecively thin film appears black in the reflection of light?
Destructive interference. If the sheet is very thin, near half the wavelength of the incident light then light reflected from the top layer is out of phase with light reflected from the bottom layer. These two reflected light waves will cancel each other out.
Do other forms of radiation from the electromagnetic spectrum also travel at the speed of light?
Yes, all forms of electromagnetic radiation, including gamma rays, X-rays, visible light, ultraviolet light, infrared light, microwaves, and radio waves, travel at the same speed in a vacuum, which is the speed of light.
What is the sensitivity directly proportional to in atomic absorption spectrometry?
The sensitivity is directly proportional to the number of atoms in ground state.
Why spectrophotometer at 405nm is used to analyze alkaline phosphatase?
because it is very powerful than other spectrophotometers
What Elements Are Present In The Star Sirius?
Hydrogen and helium are the most abundant elements in a star.
