Physics

Electromagnetic waves are all the same phenomenon—light traveling at a constant speed—but they vary in how tightly their peaks are packed together. Wavelength and frequency are inversely related: shorter wavelengths oscillate more times per second (higher frequency), while longer wavelengths complete fewer cycles in the same distance (lower frequency). The key insight is that this relationship $c = \lambda f$ is fixed by the speed of light, so you can't change one without the other changing in the opposite direction.
