What does the speed of light equation (c=fλ) represent?

The equation for the speed of light, expressed as c = fλ, illustrates the relationship between the speed of light (c), frequency (f), and wavelength (λ) of electromagnetic radiation. In this formula, the speed of light is a constant value in a vacuum, approximately 3.00 x 10^8 meters per second. The frequency represents how many wave cycles pass a point in one second, while the wavelength indicates the distance between successive crests (or troughs) of the wave.

This equation reveals that as frequency increases, wavelength decreases, and conversely, as frequency decreases, wavelength increases, while the speed of light remains constant. This fundamental relationship is crucial in understanding various phenomena in physics and chemistry, including the behavior of light and electromagnetic waves.

The other options do not accurately represent the scope of the equation. While energy conversions and particle behavior are important concepts, they are not directly expressed through the speed of light equation itself.
