Consider two astrophysical sources with blackbody radiation. The first radiation peaks at an average, classical, X-ray wavelength and another at γ-ray frequency (ν=10^22 Hz). What is their temperature? Assuming that the first is emitted from a source at redshift (z) = 2.8, what should be the frequency observed from a satellite orbiting our planet? What kind of radiation would be observed from Earth?

Scenario III Another student, this time a biology undergraduate student (interested in biophysics), decides to travel to Bethesda MD (NIH) to study the effects of electromagnetic radiation on normal skin cells in white mice. Over the course of the summer, he irradiates a portion of the mouse skin using IR radiation (6000 nm), gamma 15 radiation (10 Hz), visible radiation (600 nm), UV radiation (2 X 10 Hz), and microwave radiation (10 cm) By using electron microscopy and other techniques,...

Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...

Background (Part 1): We are continuously exposed to ionizing radiation from natural and artificial sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground and cosmic radiation to man-made sources such as medical x-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 620 millirem. In this activity, you will use the interactive online dose calculator to estimate...
