Question

What is the relationship between pho Thanh energy and the color of light

Violet photons have the least amount of energy
All colors have the same photon energy
Red photons have the most energy
Red photons have the least amount of energy

Answer 1

Red photons have the least amount of energy

Step-by-step explanation:

The relationship between the photon energy and the color of light is given by:

`E=(hc)/(\lambda)`

where

E is the energy

h is the Planck constant

c is the speed of light

`\lambda` is the wavelength (which determines the color of light)

As we see from the equation, energy and wavelength are inversely proportional: this means that the longer the wavelength, the lower the energy, and viceversa.

Among the colors in the visible light spectrum, red is the color with longest wavelength (620-750 nm) and violet is the color with shortest wavelength (380-450 nm). This means that red photons have the least amount of energy, while violet photons have the greatest amount of energy.

So the correct choice is

Red photons have the least amount of energy
