What is the difference between AAS and Flame photometer?
flame photometry is a type of atomic EMISSION spectroscopy. The sample is excited (raised to a high temperature), causing the emission of light. the wavelength of the emitted light is a function of the energy of the excited electrons, so each element has a characteristic set of wavelengths. usually a single wavelength is detected and the intensity of the emission is used to calculate concentration. Atomic adsorption works in the reverse way. A light of a standard wavelength (a wavelength characteristic of the target element) is passed through a flame containing the unknown substance, and the concentration of the target element is determined by the reduction in the energy of this light as it passes through the flame. the light is adsorbed by the electrons in the target element, kicking them into a higher orbit or completely out of the atom, depending on the energy involved. basically, one method involves the emission of the energy as an excited electron kicks back down to a lower state, and the other involves the adsorption of energy as an electron is kicked up an energy state. Same basic principle-change in electron energy relates to light of a specified wavelength and the change in the amount of that light can be measured and converted to a concentration.
What is the series of molecules through which excited electrons are passed down a thyroid membrane called?
electron transport chain
What is light source that has only one wavelength of light and will not spread out when passed through a prism is defined as?
A laser is a light source that has only one wavelength of light and will not spread out when passed through a prism. The light produced by a laser is coherent, meaning all the photons are in phase with one another.
What happens when an excited electron is passed to an electron acceptor in a photosystem?
When an excited electron is passed to an electron acceptor in a photosystem, it creates an electron transport chain that helps generate energy in the form of ATP and NADPH through a series of redox reactions. This process is a crucial step in photosynthesis that ultimately contributes to the production of glucose and other organic molecules.
Which colour of a light shows maximum deviation when passed through a prism?
Violet
Why did each gas only show a color when electricity was passed through it?
When electricity is passed through a gas, it causes the gas atoms or molecules to become excited and emit light at specific wavelengths. Each gas has a unique set of energy levels, so when electricity is passed through it, the emitted light will reveal the characteristic color associated with that specific gas.
What happens when an electric current is passed through the gas of vapor of an element?
When an electric current is passed through a gas or vapor of an element, it can cause the gas or vapor to ionize and emit light. This process is known as a gas discharge or glow discharge and is commonly seen in neon signs or fluorescent lights. The color of the light emitted depends on the element present in the gas or vapor.
What is the series of molecules down which excited electrons are passed in a thylakoid membrane?
thylakoids
What is the series of molecules down which excited electrons are passed a thylakoid membrane?
thylakoids
Which is the series of molecules through which excited electrons are passed down a thylakoid membrane?
The series of molecules through which excited electrons are passed down a thylakoid membrane during photosynthesis is called the electron transport chain. This chain consists of various protein complexes and molecules, such as plastoquinone, cytochrome b6f complex, and plastocyanin, that work together to transfer electrons and generate a proton gradient used to produce ATP.
When white light passed through prism the colour which has least deviation?
The color that undergoes the least deviation when white light passes through a prism is red. This is because red light has the longest wavelength amongst the colors of the visible spectrum, which results in less bending when passing through the prism compared to the shorter wavelength colors like violet or blue.
If three crests of a wave pass by a point how many complete wavelengths have passed by the point?
If three crests of a wave pass by a point, then one complete wavelength has passed by the point. Each crest represents one wavelength, so three crests equal three-quarters of a complete wavelength.
