Photon energy, frequency, wavelength, and Planck’s constant are inextricably linked in a fundamental relationship. The energy of a photon, measured in units of electronvolts (eV), is directly proportional to its frequency, which represents the number of electromagnetic waves passing a given point per second. Conversely, it is inversely proportional to its wavelength, which is the distance between two consecutive peaks or troughs of the wave. This relationship is defined by Planck’s constant, a fundamental physical constant that provides a bridge between the energy and frequency of a photon.
Explain the basic concepts of frequency, wavelength, energy, Plank’s constant, and speed of light in the context of electromagnetic radiation.

Quantum Mechanics: The Invisible Puppet Master
Prepare to enter the realm of the quantum, where the rules of physics get a little…trippy. Quantum mechanics is the study of the microscopic world, where things behave in ways that defy our everyday experience. And when it comes to electromagnetic radiation, quantum mechanics holds the key to understanding its wave-particle duality.
Wait, what’s that? Wave-particle duality means that electromagnetic radiation acts like both a wave and a particle. How’s that possible? Well, in the quantum world, things can be both and. It’s like a cat that’s simultaneously alive and dead, until you open the box. Or, in this case, until you measure the radiation.
When electromagnetic radiation is measured, it acts like a particle. But when it’s just cruising along, it behaves like a wave. This duality is fundamental to understanding how electromagnetic radiation interacts with matter.
The Wave: Meet Your Rhythm
Think of the wave as a wiggle in space. It’s like a cosmic accordion, stretching and squeezing as it travels. The wavelength is the distance between two peaks of the wiggle, and the frequency is how often the wiggle repeats itself in time.
