Question

Which photon has more energy?

a. a photon of green light
b. a photon of infrared radiation
c. a photon of yellow light
d. a photon of red light
e. a photon of ultraviolet radiation​

Answer 1

To determine which photon has more energy, we need to consider the relationship between energy and wavelength or frequency.

Energy is directly proportional to frequency and inversely proportional to wavelength. This means that photons with higher frequencies or shorter wavelengths have more energy, while photons with lower frequencies or longer wavelengths have less energy.

Let's consider the options given:

a. Green light: Green light has a relatively shorter wavelength compared to red and yellow light, but longer than ultraviolet radiation. Therefore, it has more energy than red and yellow light, but less energy than ultraviolet radiation.

b. Infrared radiation: Infrared radiation has a longer wavelength than green, yellow, and red light. Therefore, it has less energy compared to green, yellow, and red light, but more energy compared to ultraviolet radiation.

c. Yellow light: Yellow light has a longer wavelength compared to green light but shorter than red light. Therefore, it has less energy compared to green and ultraviolet radiation, but more energy compared to red light.

d. Red light: Red light has the longest wavelength compared to green, yellow, and ultraviolet radiation. Therefore, it has less energy compared to green, yellow, and ultraviolet radiation.

e. Ultraviolet radiation: Ultraviolet radiation has the shortest wavelength among the given options. Therefore, it has the highest energy among the given options.

In summary, the photon of ultraviolet radiation (e) has the most energy, while the photon of red light (d) has the least energy among the given options.

Answer 2

e. a photon of ultraviolet radiation

Step-by-step explanation:

The photon of ultraviolet radiation has more energy than the photons of green light, infrared radiation, yellow light, and red light.

This is because the energy of a photon is directly proportional to its frequency. Ultraviolet radiation has the highest frequency of all the visible light colors, so it has the most energy per photon.

So, the answer is: e. a photon of ultraviolet radiation

The frequencies and energies of the visible light colors are:

`\textsf{ Violet: frequency of $\sf 7.5 * 10^(14) $ Hz and energy of 3.1 eV}`

`\textsf{ Blue: frequency of $\sf 6.2 * 10^(14) $ Hz and energy of 2.7 }`

`\textsf{Green: frequency of $\sf 5.4 * 10^(14)$ Hz and energy of 2.2 eV}`

`\textsf{Yellow: frequency of $\sf 5.0 * 10^(14 )$ Hz and energy of 2.0 eV}`

`\textsf{Orange: frequency of $\sf 4.8 * 10^(14)$ Hz and energy of 1.9 eV}`

`\textsf{Red: frequency of $\sf 4.5 * 10^(14)$ Hz and energy of 1.8 eV }`
