This short slide show applies the electromagnetic spectrum to astronomy. First, electromagnetic radiation is introduced to viewers. Wavelength is defined and its unit of measurement explained. Finally, aspiring astronomers find that the electromagnetic spectra given off by a star can provide its composition, temperature, and more!
Students explore the nature of electromagnetic spectrum through a series of experiments. In this physics instructional activity, students determine how light behaves under certain circumstances. They explain how humans perceive colors.
Students examine general properties of electromagnetic waves, identify position of each type of radiation in spectrum, discuss methods used to detect and analyze waves, and analyze relation between specific wave properties and their position in spectrum.
In this chemistry instructional activity, students study the Bohr atomic model and calculate the wavelength and frequency of given electromagnetic radiation. They answer 9 problems and short answer questions.
Four modules are a part of this stellar lesson plan. Space scientists view the electromagnetic spectrum, they generate waves on a computer screen in order to measure frequency and wavelength, discover how light is related to temperature, and finally relate their learning to the temperature of stars. Much of this lesson is taught via an interactive website. There is so much terrific material here that you could spend an entire week on this topic!
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 for work functions, and more. There are multiple choices to choose from for the answers, which will help beginning photoelectric physicists make sure they are on the right wavelength!
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 brightness of the system. This is a terrific space science investigation or practical application of ratios and proportions.
This is a review of specific textbook chapters for an honors chemistry course. Although the reading assignment may not be available, the questions could be used for any honors chemists as a comprehensive review. It assesses the understanding of various atomic models and electromagnetic radiation (frequency and wavelength). Be aware that the assignment requires an exceptional amount of writing and will require ample time to complete.
Young scholars engage in a lesson plan which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.
Part of a larger online space science website, this page has a brief explanation of electromagnetic radiation and a chart of wavelengths as compared to common objects. There are four questions to answer about the information. This can be used in your physical science class when covering electromagnetic waves or as part of a space science curriculum. Be sure to check out the contents link at the bottom of the page for other related resources by the Galileo Outreach Coordination Team.
