Updated: 2/7/2025

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.

How much is 1lb 8oz in grams?

1 lb 8 oz is equivalent to approximately 680 grams.

How much oxygen does an E cylinder hold?

An E cylinder typically holds around 680 liters of oxygen when filled to its working capacity at a pressure of 2,200 psi. This can vary slightly based on the manufacturer and filling pressure.

What is the lattice energy of CsI?

The lattice energy of CsI (cesium iodide) is approximately 680 kJ/mol. It is the energy released when gaseous ions come together to form a solid lattice in an ionic compound.

What type of chemical bond is BeS?

BeS forms an ionic bond. Beryllium (Be) is a metal that tend to lose electrons, while sulfur (S) is a nonmetal that tends to gain electrons. In BeS, Be transfers its electrons to S, resulting in the formation of an ionic compound.

Why is chlorophyll a also called chlorophyll 680?

Chlorophyll a is also called chlorophyll 680 due to its peak absorption of light at a wavelength of 680 nm. This specific absorption wavelength corresponds to the optimal energy level needed for chlorophyll a to carry out the process of photosynthesis efficiently.

What is the wavelength of solar energy used for photosynthesis?

680 nanometers to 700 nanometers is about optimum for the photosynthetic rate but there are other wave lengths that plants do use.

What is the wavelength of 680 Hz tone moving through air?

The wavelength of a 680 Hz tone moving through air can be calculated using the formula: wavelength = speed of sound / frequency. The speed of sound in air at room temperature is approximately 343 m/s. Therefore, the wavelength of a 680 Hz tone in air would be about 0.504 meters (504 mm).

What is the frequency of a light with a wavelength of 680 NM?

The frequency of light can be calculated using the formula f = c/λ, where f is the frequency, c is the speed of light (approximately 3.00 x 10^8 m/s), and λ is the wavelength. Converting the wavelength of 680 nm to meters (680 nm = 6.8 x 10^-7 m) and plugging into the formula gives: f = (3.00 x 10^8 m/s) / (6.8 x 10^-7 m) ≈ 4.41 x 10^14 Hz.

What is the difference between photosystem one and two?

Photosystem I absorbs light best at a wavelength of 700 nm, while Photosystem II absorbs light best at a wavelength of 680 nm. Photosystem I transfers electrons to reduce NADP+ to NADPH, while Photosystem II replenishes electrons lost in the process of photosynthesis. Both photosystems work together in the light-dependent reactions of photosynthesis to ultimately produce ATP and NADPH.

Where do electrons get their energy from in photo system II?

PSII is a protein that is filled with chlorophyll, specifically P680. This chlorophyll captures the energy of light (light that has a wavelength of 680). That energy is used to split a water molecule into O2 and a hydrogen ion (an electron) and excites that electron that is then passed down the electron transport chain to PSI (filled with P700) where the energy in the light of the wavelength of 700 is used to excite it further.
