This module simulates the excitation of hydrogen atoms through irradiation with electromagnetic radiation of different wavelengths.

This site from Georgia State University gives information on the transitions of electrons between energy levels. The energy levels for electrons in the hydrogen atom are discussed. The Rydberg equation is stated and electron transitions...

In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine...

A short description of a physics lab involving the determination of the wavelength of the four spectral lines in the hydrogen emission spectrum. Perhaps the most important part of the page is the picture of the spectrometer.

[Free Registration/Login Required] Neon lights are a type of discharge tube. Observe how electrons create colored light in a hydrogen gas discharge tube. Can you figure out why hydrogen's emission spectrum contains more than one color of...

This site provides background information, images, and an activity to help students understand the concept of radiation. Includes both the student pages and a teachers guide with lesson plan.

This site details what radiation is, the physics of radiation, and radiative transfer as it occurs in nature. Content explores the electromagnetic spectrum, electromagnetic waves, properties of radiation, and solar radiation.

Here is a 1-5 day unit on electromagnetic radiation that features a teacher guide and student activities with extensions.
