Emission spectroscopyis a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according to its electronic structure, by observing these wavelengths the elemental composition of the sample can be determined.
Absorption spectroscopy measures the loss of electromagnetic energy after it illuminates the sample under study. For example, if a light source with a broad band of wavelengths is directed at a vapour of atoms, ions, or molecules, the particles will absorb those wavelengths that can excite them from one quantum state to another.

What are the differences between titanium oxide and titanium dioxide in terms of their properties and applications?
Titanium oxide and titanium dioxide are the same compound, with the chemical formula TiO2. They are used interchangeably in various industries.
What are the differences between chemiluminescence and fluorescence in terms of their mechanisms and applications?
Chemiluminescence is the emission of light resulting from a chemical reaction, while fluorescence is the emission of light when a substance absorbs light energy and then re-emits it. Chemiluminescence does not require an external light source, while fluorescence does. Chemiluminescence is often used in analytical chemistry for detecting substances, while fluorescence is commonly used in biological imaging and medical diagnostics.
What are the differences between column chromatography and sublimation in terms of their principles and applications?
Column chromatography separates compounds based on their different affinities for a stationary phase, while sublimation separates compounds based on differences in their volatility. Column chromatography is commonly used in purifying mixtures of compounds, while sublimation is often used to purify solids that can sublime.
What are the differences between tryptone and peptone in terms of their composition and functionality in microbiological media?
Tryptone and peptone are both protein derivatives used in microbiological media. Tryptone is a partially digested form of casein, while peptone is a mixture of amino acids and peptides derived from protein hydrolysis. Tryptone provides a source of amino acids and peptides for bacterial growth, while peptone serves as a nitrogen source and helps support microbial growth in culture media.
What are the differences between xylan and Teflon in terms of their properties and applications?
Xylan is a natural polymer found in plant cell walls, while Teflon is a synthetic polymer known for its non-stick properties. Xylan is biodegradable and used in food packaging and coatings, while Teflon is heat-resistant and used in cookware and industrial applications.
What are the differences between rotors and discs in terms of their performance and functionality in a braking system?
Rotors and discs are actually the same component in a braking system. They are both used to refer to the flat, circular metal component that rotates with the wheel and is clamped by the brake pads to slow down the vehicle. So, there are no differences between rotors and discs in terms of their performance and functionality in a braking system.
What are the differences between black and white electrical wires in terms of their functions and applications?
Black electrical wires are typically used as hot wires to carry electrical current from a power source to a device. White electrical wires are usually used as neutral wires to complete the circuit and return the current to the power source. The color coding helps electricians identify and properly connect the wires for safe and efficient electrical systems.
What are two major differences between numbers used in math and numbers used doing physics?
There are no differences in the numbers.
What are the differences between commercial licenses and other licenses, and how do they impact the use and distribution of software products?
Commercial licenses are typically used for software that is sold for profit, while other licenses, such as open-source licenses, allow for free distribution and modification of the software. Commercial licenses often restrict how the software can be used and distributed, while other licenses may have fewer restrictions. These differences impact how software products can be used, shared, and distributed, depending on the terms of the specific license.
What is the difference between successive terms?
The difference between successive terms refers to the change or gap in value between consecutive elements in a sequence or series. It is calculated by subtracting the earlier term from the later term. For example, in the sequence 2, 5, 9, the differences between successive terms are 3 (5 - 2) and 4 (9 - 5). This concept is often used in analyzing patterns or trends in mathematical sequences.
What are the differences between titanium oxide and titanium dioxide in terms of their properties and applications?
Titanium oxide and titanium dioxide are the same compound, with the chemical formula TiO2. They are used interchangeably in various industries.
What word is used to describe differences between organisms?

What is interstellar differences?
"Interstellar" means "between the stars". "Interstellar differences" is not a term commonly used in astronomy.
What are the differences between nits and lux in terms of measuring display brightness?
Nits measure the brightness of a display in terms of light output, while lux measures the brightness of the display in terms of the amount of light that reaches a surface. Nits are used to quantify the brightness of the display itself, while lux is used to measure the brightness of the display as it is perceived by the viewer.
What are the differences between methane, propane, and butane in terms of their properties and uses?
Methane, propane, and butane are all hydrocarbons, but they differ in their chemical structures and properties. Methane is the simplest and lightest, while propane and butane are heavier and have higher boiling points. Propane and butane are commonly used as fuels for heating and cooking, while methane is mainly used as a source of energy in natural gas.
What are the differences between cambur and guineo?
Cambur and guineo are both terms used to refer to bananas in different Spanish-speaking regions. In general, "cambur" is more commonly used in Venezuela and some parts of Colombia, while "guineo" is more commonly used in the Caribbean and Central America. However, both terms can be used interchangeably to refer to the same fruit.
What are the differences between an inverted and upright microscope in terms of their design and functionality?
An inverted microscope has its light source and condenser located below the stage, while an upright microscope has them above the stage. Inverted microscopes are commonly used for observing living cells in culture dishes, while upright microscopes are more versatile for various types of samples.
