Question

1. compared to a photon of orange light, which of the following is greater for a photon of green light? select two correct answers energy wavelength frequency speed period

Explanation:

1. Recall the electromagnetic spectrum: Green light has a shorter wavelength than orange light. The relationship between wavelength ($\lambda$), frequency ($f$), and speed of light ($c$) is $c = \lambda f$ (where $c$ is constant in a vacuum). So, shorter wavelength means higher frequency.
2. The energy of a photon is given by $E = hf$ (where $h$ is Planck's constant). Since green light has a higher frequency than orange light, its photon energy is higher.
3. The speed of light (photon speed) in a vacuum is constant for all colors, so speed is not greater. The period $T=\frac{1}{f}$, so a higher frequency means a smaller period. Wavelength of green is shorter than orange, so wavelength is not greater.

Answer:

A. energy, C. frequency
