Concept explainers
Consider the following debate between two students regarding the energy given off by the Sun.
Student 1: I think that the Sun gives off most of its energy at ultraviolet
Student 2: Even though UV photons are more energetic than visible photons, the Sun simply gives off fewer ultraviolet photons and gives off way more visible and infrared photons. So I think that these longer wavelength photons account for most of the energy coming from the Sun.
Do you agree or disagree with either or both of these students? Explain your reasoning.

- What is the wavelength in meters observed with a frequency of (4.5x10^15)? Answer with 2 significant figures and it must be in scientific notation. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10 unitsarrow_forwardDescribe the electromagnetic spectrum in a few sentences, including a diagram of the wavelength regions and typical applications in those regions.arrow_forwardSuppose YOUR body temperature averages 98.6 F. 1. How much radiant energy in Wm^-2 is emitted from YOUR body? 2. What is the total radiant energy in W that is emitted from YOUR body? 3. At what wavelength does YOUR body emit the largest amount of radiant energy?arrow_forward
- Tutorial Star A has a temperature of 5,000 K and Star B has a temperature of 6,000 K. At what wavelengths (in nm) will each of these star's intensity be at its maximum? If the temperatures of the stars increase, the wavelength of maximum intensity. What is the temperature (in K) of a star that appears most intense at a wavelength of 829 nm? Part 1 of 4 Wien's Law tells us how the temperature of a star determines the wavelength of maximum intensity or at what wavelength the star appears brightest. 2.90 x 106 TK If the temperature is in kelvin (K) then A is in nanometers (nm). Anm ^A = AB = = Part 2 of 4 To determine the wavelengths of maximum intensity for the two stars: 2.90 x 106 2.90 x 106 K nm nmarrow_forwardQuestion 9 Look at the three spectra of stars in the picture above. The top one, for instance, is the darkest at the blue end and the brightest at the red end. Using such considerations, list the top, middle and bottom spectra in order of temperature, highest to lowest.arrow_forwardThe greenhouse effect can be explained easily if you understand the laws of blackbody radiation. A greenhouse gas blocks the transmission of infrared light. Given that the incoming light to Earth is sunlight with a characteristic temperature of 5800 K (which peaks in the visible part of the spectrum) and the outgoing light from Earth has a characteristic temperature of about 300 K (which peaks in the infrared part of the spectrum), explain how greenhouse gases cause Earth to warm up. As part of your answer, discuss that greenhouse gases block both incoming and outgoing infrared light. Explain why these two effects don’t simply cancel each other, leading to no net temperature change.arrow_forward
- Continuing the thinking in Exercise 29.27 and Exercise 29.28, calculate the energy in a cubic meter of space, multiply the energy per photon calculated in Exercise 29.26 by the number of photons per cubic meter given above.arrow_forwardComplete the following chart by using Wien's law for blackbodies. You may use a calculator and the Wien's law formula, and/or the interactive graph, to calculate the wavelength when given a temperature. Use the data table Blackbody Temperatures of the Electromagnetic Spectrum to identify the region of the electromagnetic spectrum where an object with the stated temperature emits most of its light. max (angstroms) Star Capella Sun Procyon Aldebaran Formalhaut Submit Answer T (kelvins) 4,940 5,780 6,530 4,010 8,200 EM Region ---Select--- ---Select--- Radio Microwave Infrared Visible Ultraviolet X-ray V Gamma Rayarrow_forwardOur Sun has a surface temperature of about 5800 K.

- Tutorial Star A has a temperature of 5,000 K. How much energy per second (in J/s/m2) does it radiate from a square meter of its surface? If the temperature of Star A decreases by a factor of 2, the energy will decrease by a factor of Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate from a square meter of its surface? Part 1 of 4 The energy of a star is related to its temperature by E = GT4 where σ = 5.67 x 10-8 J/s/m2/K4. Part 2 of 4 To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA. EA = J/s/m² Submit Skip (you cannot come back)arrow_forwardUse Wien's Law to calculate the peak wavelength of light coming from the Sun. Assume T=5800 K for the surface temperature of the Sun. Wein's displacement law says that the blackbody temperature and peak wavelength multiplied together give a constant of 0.29 cm-K. (K is degrees Kelvin). Convert the wavelength from part A into a frequency. The product of wavelength and frequency for electromagnetic radiation is a constant, the speed of light (c), 3 x 10^10 cm/s.arrow_forwardTutorial Star A has a temperature of 6,000 K. How much energy per second (in J/s/m²) does it radiate onto a square meter of its surface? If the temperature of Star A decreases by a factor of 2, the energy will decrease by a factor of Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate onto a square meter of its surface? Part 1 of 4 The energy of a star is related to its temperature by E = OTA where o = 5.67 x 10-8 J/s/m²/K4. Part 2 of 4 To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA. EA J/s/m²arrow_forward
