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) All of the above are true.

Question

Quizplus · Accepted Answer

The speed of light is constant, which means that as wavelength increases, frequency must decrease. This is described by the equation c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency. Therefore, option A is true. Option B is incorrect because radio waves have longer wavelengths than gamma rays. Option C is also unrelated to the constant speed of light.
