Which process is most directly driven by light energy?

Convert 4.5 x 10^-15 J/photon to wavelength in nm. Which of the following is the correct wavelength?

Electromagnetic radiation with a wavelength of 531 nm appears as green light to the human eye. The energy of one photon of this light is 3.74 × 10^-19 J. Thus, a laser that emits 1.3 × 10^-2 J of energy in a pulse of light at this wavelength produces how many photons?

How much energy is contained in one mole of X-ray photons with a wavelength of 0.280 nm in kJ/mol?

What is the energy in kJ/mol of infrared radiation with a wavelength of 1.51 × 10⁻⁶ m?

Which of the following processes is most directly driven by light energy?

In photosynthesis, what is the energy of a photon first used to do?

Which example involves the transformation of chemical energy directly into light energy?

What is the source of energy that provides the boost for electrons during photosynthesis?
