Los carotenos, que están presentes en todos los organismos capaces de hacer la fotosintesis, extienden la gama de luz absorbida por el organismo. Su capacidad máxima de absorción de luz está en el intervalo de 440 a $470 \mathrm{~nm}$. Calcule la energía representada por la absorción de un número de Avogadro de fotones con longitud de onda de $455 \mathrm{~nm}$.

Key Concepts

Photon Energy Calculation

This concept involves determining the energy of a single photon using the formula E = hc/?, where h is Planck's constant, c is the speed of light, and ? is the wavelength of the light. It is a fundamental principle in quantum mechanics that establishes the relationship between a photon's energy and its electromagnetic properties.

Planck's Constant

Planck's constant (h) is a fundamental constant in quantum mechanics that relates the energy of a photon to its frequency. It is pivotal in the quantization of energy and appears in various formulas throughout the field of modern physics.

Speed of Light

The speed of light (c) is the constant speed at which light waves propagate in a vacuum. It plays a crucial role in the calculation of photon energy and is a central parameter in physical equations involving electromagnetic radiation.

Avogadro's Number

Avogadro's number provides the number of particles (or photons, in this case) in one mole. It is used to scale the energy of a single photon up to the energy for a mole of photons, linking microscopic properties to macroscopic quantities.

Unit Conversion

Unit conversion, particularly converting nanometers to meters, is essential for ensuring that the values used in the formula are in consistent SI units. This maintains the accuracy of the calculated energy and is a fundamental practice in physics and engineering calculations.
