BlackTom AI · Accepted Answer

To determine which wavelength corresponds to the highest energy, recall the photon energy relation E = hc/λ, meaning energy is inversely proportional to wavelength.

Option 450 nm: This is a relatively short wavelength, but not the shortest in the list. Since energy scales inversely with wavelength, 450 nm will have more energy than longer wavelengths like 650 nm or 750 nm, but we’re not yet identifying the peak.

Option 750 nm: This is among the longest wavelengths here (red region). Longer wavelengths mean lower photon energy, so this choice yields less energy than shorter wavelengths such as 450 nm or 380 nm.

Option 550 nm: This sits in the green/yellow part of the spectrum. It is shorter than 650 nm and 750 nm, so it has higher energy than those longer wavelengths, but still not necessarily the highest among the options.

Option 380 nm: This is in the near ultraviolet region and is the shortest wavelength in the provided set. Because energy increases as wavelength decreases, 380 nm delivers more energy per photon than all the longer wavelengths listed here.

Option 650 nm: This is another red/orange wavelength, longer than 450 nm and 550 nm, so its photons have lower energy than those with shorter wavelengths like 450 nm and 380 nm.

Putting the comparisons together, the smallest wavelength in the list yields the greatest energy per photon, while the longer wavelengths correspond to progressively lower energies. Therefore, among the given options, the one with the shortest wavelength will have the highest energy.
