This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...

The University of Hawaii has published a vast collection of midterm and final exams for their Physics 152 course. This particular exam offers a variety of assessment methods, and covers the topic of electromagnetic radiation....

Take young naturalists on an exploration of the world's tropical rainforests with this extensive collection of lessons and activities. Whether its creating leaf and flower prints or investigating the absorption spectrum of...

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required...

True-false and multiple-choice questions are posed in Part A of this exam, covering the topic of electromagnetic radiation. In Part B, problems relating to refraction must be solved. This is a well-rounded exam that will help you...

A two-hour final exam covers a range of physics topics related to electricity and magnetism. It employs a variety of methodologies for assessing your physics learners' understanding and mastery of these concepts. You will need to review...

High schoolers investigate the absorptivity of different colored food dyes. For this chemistry lesson, students explain how we see colors. They construct a graph of absorbance comparred with wavelength using experimental data.

Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

NOAA has produced a series of topic papers for use by teachers and students. This paper is on the increase of radio wave activity and the effects solar emissions have on it. PDF format.

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

This site from IPAC is a series of images of various celestial objects and regions as viewed in infrared light. Each photo is accompanied by a caption.

Solar flares are huge explosions on the Sun that emit lots of electromagnetic radiation.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

This page defines electromagnetic radiation. Included are links to more information.
