A photon of red light has:
Group of answer choices
more energy than a photon of blue light
There is no such thing as a red photon because red is a mixture of light at different frequencies.
a higher frequency than a radio photon
a higher frequency than a photon of blue light
less energy than a radio photon
a lower frequency than a photon of blue light
A photon of red light has a lower frequency than a photon of blue light.
The correct answer is: a higher frequency than a photon of blue light.
To understand why a photon of red light has a higher frequency than a photon of blue light, we need to understand the relationship between frequency and wavelength.
Light, including red and blue light, consists of particles called photons. Each photon has a specific frequency and wavelength. The frequency of a photon refers to the number of times it oscillates or vibrates per second, while the wavelength refers to the distance between two consecutive peaks or troughs of the light wave.
The relationship between frequency and wavelength is inverse: as the frequency of a photon increases, its wavelength decreases, and vice versa. This relationship is described by the equation: speed of light = frequency x wavelength.
Now, red light has a longer wavelength compared to blue light. Since frequency and wavelength are inversely related, a longer wavelength corresponds to a lower frequency. Therefore, a photon of red light has a lower frequency than a photon of blue light.
From the given answer choices, we are looking for the option that is opposite to this explanation. Therefore, we can eliminate the choices that suggest a lower frequency for red light.
The remaining choices are:
- More energy than a photon of blue light
- A higher frequency than a radio photon
- Less energy than a radio photon
From these choices, we can eliminate the option suggesting less energy than a radio photon because radio photons generally have lower energy compared to visible light photons.
Hence, the correct answer is: a higher frequency than a photon of blue light.
