15 Νοε 2023 · Learning Objectives. Investigate how the spectrum of electromagnetic radiation emitted by objects is affected by the object’s temperature using the Blackbody Spectrum simulation. Wien's Law and Stefan-Boltzmann Law. Recall the relationship between peak wavelength and temperature according to Wien's Law: 𝜆𝑚𝑎𝑥 =2.9×106 𝑛𝑚∙𝐾, 𝑇.
How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of Sirius A, the sun, a light bulb, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change.
Use the simulation data's, peak wavelength to find the numerical temperature of Sirius A. and more. Study with Quizlet and memorize flashcards containing terms like Slide the temperature button on the phet colorado simulation up to Sirius A.

a. What part of the EM spectrum would be useful to determine the surface temperature of objects such as asteroids? Explain your answer. Infrared b. The surface of Mars appears reddish. Is Mars ‘red-hot’? If so, what is its surface temperature? If not, where is the red light coming from?
In this lab you will use an incandescent light bulb and a prism spectrometer to measure the blackbody spectrum. Although a light bulb is not a blackbody (it emits much more radiation than it absorb!) it is a good approximation of a grey body: an object that emits a fraction of the blackbody spectrum with the same frequency distribution.
Activity: Exploring Blackbody Radiation using the PhET Simulation. Purpose. • To understand the blackbody radiation graph and its applications. Materials. • A computer with access to the internet. Background. Everything emits Electromagnetic (EM) radiation. The sun does, operating incandescent lights do. We do.
