The absorption spectrum of argon has a line at 515 nm what is the energy of this line?
3.86 x 10-19 J
Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?
Transition B produces light with half the wavelength of Transition A, so the wavelength is 200 nm. This is due to the inverse relationship between energy and wavelength in the electromagnetic spectrum.
What is the absorption spectrum of NITROGEN DIOXIDE?
The absorption spectrum of nitrogen dioxide is in the ultraviolet region, with absorption peaks around 400-500 nm. These peaks correspond to transitions in the molecule that involve the excitation of electrons to higher energy levels. Nitrogen dioxide is a brownish gas due to its absorption properties in the visible range.
What is the UV visible spectra of Congo red?
Congo red has a characteristic UV-visible absorption spectrum with absorption peaks around 490-500 nm and 330-340 nm due to its extended conjugated system. These peaks correspond to the red and blue colors observed when Congo red is in solution.
What is the strength of a bond that can be broken by absorption of a photon of 420 light?
A bond that can be broken by absorption of a photon of 420 nm light would likely have a bond energy lower than the energy of a photon with that wavelength. This implies that the bond is relatively weak, such as in the case of π-bonds in organic molecules or weak hydrogen bonds.

What is the second longest wavelength in the absorption spectrum of hydrogen?
The second longest wavelength in the absorption spectrum of hydrogen corresponds to the transition from the n=2 to n=4 energy levels. This transition produces a spectral line known as the H-alpha line, which falls in the red part of the visible spectrum at a wavelength of 656.3 nm.

What element has an emission line at 768 nm?
The element that emits a spectral line at 768 nm is hydrogen. The 768 nm spectral line corresponds to the transition of an electron from the 5th energy level to the 2nd energy level in a hydrogen atom.
Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?
Transition B produces light with half the wavelength of Transition A, so the wavelength is 200 nm. This is due to the inverse relationship between energy and wavelength in the electromagnetic spectrum.
What is the wavelength of the hydrogen atom in the 2nd line of the Balmer series?
The wavelength of the hydrogen atom in the 2nd line of the Balmer series is approximately 486 nm. This corresponds to the transition of an electron from the third energy level to the second energy level in the hydrogen atom.
Which transition occurs when light wavelength of 486 nm is emitted by a hydrogen atom?
The transition from energy level 4 to energy level 2 occurs when a hydrogen atom emits light of 486 nm wavelength. This transition represents the movement of an electron from a higher energy level (n=4) to a lower energy level (n=2), releasing energy in the form of light.
What is the shortest wavelength radiation in balmer series?
The shortest wavelength radiation in the Balmer series is the transition from the n=3 energy level to the n=2 energy level, which corresponds to the Balmer alpha line at 656.3 nm in the visible spectrum of hydrogen.

What wavelengths of light does chorophyll a asborb best?
Chlorophyll a primarily absorbs light in the blue (450-480 nm) and red (650-700 nm) regions of the electromagnetic spectrum. This absorption allows chlorophyll a to participate in photosynthesis, converting light energy into chemical energy for the plant.
What is the significance of the wavelength 680 nm in the context of photosynthesis?
The significance of the wavelength 680 nm in photosynthesis is that it corresponds to the peak absorption of light by chlorophyll a, the primary pigment responsible for capturing light energy during the light-dependent reactions of photosynthesis. This specific wavelength is optimal for driving the process of photosynthesis and converting light energy into chemical energy.
