The fact that the speed of light is constant as it travels through a vacuum means that:
A) photons with longer wavelengths have lower frequencies
B) radio wave photons have shorter wavelengths than gamma ray photons
C) X-rays can be transmitted through the atmosphere around the world
D) ultraviolet photons have less energy than visible photons
E) all of the above are true

Question

Quizplus · Accepted Answer

According to the equation c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency, if the speed of light is constant, wavelength and frequency are inversely proportional. Therefore, photons with longer wavelengths have lower frequencies.
