High schoolers explore the nature of electromagnetic spectrum through a series of experiments. In this physics lesson, students determine how light behaves under certain circumstances. They explain how humans perceive colors.
In this chemistry worksheet, students study the Bohr atomic model and calculate the wavelength and frequency of given electromagnetic radiation. They answer 9 problems and short answer questions.
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!
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!
Students engage in a lesson 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.
Electromagnetic radiation emitted by points at high temperature 13 billion years ago is only now reaching us in a uniform fashion. Sal explains the idea that this cosmic radiation may disappear as certain areas mature, as well as when the radiation from further points will reach us.
Young scholars define electromagnetic radiation, list major categories and uses of electromagnetic waves, identify potential health risks with electromagnetic waves, and demonstrate understanding of Plank's constant by solving quantitative equations on wavelength, frequency, and energy.
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!
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.
In this physics worksheet, students review vocabulary terms and key equations associated with the quantum mechanical model. Students apply the quantum theory to explain the photoelectric effect. This worksheet has 5 true or false, 12 matching, and 2 short answer questions.
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.
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 evaluate your young physicists' handle on electromagnetic radiation.
In this electromagnetic radiation and atomic structure worksheet, students answer thirteen questions about topics such as wavelength, frequency and the electromagnetic spectrum. They also answer questions about the location of electrons using the Bohr model of the atom and the quantum mechanical model of the atom.
Which is better for baking potatoes: the heat conduction of an oven or the electromagnetic radiation of a microwave? Chef Jamika tries both, and explains the physical science occurring along the way. She also emphasizes the fractional portions that she cuts the pepper into for the potato filling. So, while this is a like a cooking show, science and math topics are addressed! It would probably be most useful in your middle school physical science class when teaching about forms of energy.
It's quite a write up for a simple demonstration! Connect a nylon cord to an electric drill and generate waves. Explain that wavelength can vary according to the amount of energy added. Questions are included that you can use to guide the discussion of electromagnetic radiation and waves. Variation ideas are included to give you options if you do not have a drill handy.
Young scholars explain how cell phones work. In this physics lesson, students describe the advantages and advantages of having one. They identify the different parts of a cell phone.
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 materials, spectral lines, and more. You can use this comprehensive set of conceptual questions as an exam.
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 universe. Each part consists of three to six lessons consisting of an online reading passage and related assignment. A hands-on activity is also provided for each section. As you would expect from NASA, this unit is out of this world!
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. Multiple-choice, drawing light rays, short-answer, and problem-solving questions are available. Use this excellent resource with your advanced placement physics learners.
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.
