Concept explainers

Wien's displacement law

Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the relationship between peak wavelength and temperature.

An idealized radiating object does not reflect or scatter any radiation but instead absorbs all of the electromagnetic energy that falls on it. Can you explain why astronomers call such an object a blackbody? Keep in mind that even stars, which shine brightly in a variety of colors, are considered blackbodies. Explain why.

Answer the following A. A comet has just passed the Earth and its peak emission is observed at 15000 nm. Determine in which region of the electromagnetic spectrum (e.g. X-ray, infrared, visible, ultraviolet, ...) the peak emission wavelength resides. What is the temperature of the comet? B. Within the Solar System, a convenient unit of measurement is the Earth-Sun distance, called an astronomical unit (AU). For bigger distances, we use the light year (LY), the distance that light travels in one year. We can expand our lingo to include other measures of distance, for example, light days, light minutes, and light hours. Starting with the values you can look up in the Appendices for the speed of light and the astronomical unit, calculate how many “light minutes” there are in 1 AU. C. What is the observable universe? How big is it?
1. What is the wavelength of a radio photon from an AM radio station that broadcasts at 1470 kilohertz? Express your answer to three significant figures and include the appropriate units. 2. What is the energy of a radio photon from the same station? Express your answer to three significant figures and include the appropriate units. For question 1 I am not sure how to solve it because the frequency is in kilohertz and I don't know how to convert it into something that I can use. For the speed of light in this question, would it be best to use 3 x 10^8 m/s or 3 x 10^5 km/s? For question 2 I have the formula to use, I'm just uncertain of how to use it.
