Step 1

The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. The formula for the energy of a photon is given by $ E = h \cdot f $, where $ E $ is the energy, $ h $ is Planck's constant, and $ f $ is the Show more…

Key Concepts

Electromagnetic Spectrum

This concept covers the complete range of electromagnetic radiation, which includes radio waves, microwaves, visible light, X-rays, and more. It is fundamental to understanding how different forms of radiation vary in properties such as wavelength, frequency, and energy per photon.

Photon Energy and Frequency Relationship

The energy of a photon is directly proportional to its frequency, as described by Planck's equation (E = h?). This relationship explains why radiation with higher frequencies (such as X-rays) has greater energy per photon compared to radiation with lower frequencies (such as microwaves or FM radio waves).

Frequency-Wavelength Inverse Relationship

In the electromagnetic spectrum, frequency and wavelength are inversely related. A higher frequency means a shorter wavelength, which correlates with higher photon energy. This principle is key when ordering different types of radiation based on their energy per photon.
