Imagine you are comparing the ability of electric hot plates of different sizes and temperatures to fully cook two identical large pots of spaghetti. Note that all the pots are as large as the largest hot plate. The shading of each hot plate is used to illustrate its temperature. The darker the shade of gray the cooler the temperature of the hot plate.
If you use two hot plates of different sizes, can you assume that the hot plate that can cook a large pot of spaghetti first is at a higher temperature? Which lettered example above supports your answer?

- Suppose 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_forwarda) To which object corresponds this spectrum to? b) What is the source of radiation for each of the two humps? c) Why does the hump on the right hand side peak at higher wavelength than the hump on the left? [Specifically, what does this tell you about the temperature for each object that the light originates from?]arrow_forwardHelp me pleasearrow_forward
- Explain how we use spectral absorption and emission lines to determine the composition of a gas.arrow_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_forwardSpectrum I is showing a/an _____ spectrum created from Gas I, and spectrum II is a/an ______ spectrum created by Gas II. From the Spectrum it would be predicted that the gasses are ______arrow_forward
- 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_forwardAs we have been slowly discovering more and more about the atoms we have encountered several different models of the atoms. All of these models have issues. One of the most common issues is the scale of the subatomic particles. Like the image below The proton in this model is too large. Given the following measurement, how many protons would need to set side-by-side to to equal the width of a hydrogen atom? The radius of a proton is 0.5636 fm (Femtometer). The diameter of a hydrogen atom is 7.5 Angstroms. must be written in Scientific noation.arrow_forwardA lightbulb manufacturer makes bulbs with different "color temperatures," meaning that the spectrum of light they emit is similar to a blackbody with that temperature. Assuming the emitting areas of the filaments in two bulbs with color temperatures of 2,000 K and 4,000 K are the same, which of the two is the brighter? About how much brighter is this bulb than its companion?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_forwardA perfect black body has its surface temperature 27 cº Determine : Maximum radiation wavelength? Black body radiation intensity? The rate of energy released from 2m² Tungsten wire had its radiating surface area 8mm² and its temperature 2100K, considering that the wire is an ideal black body, Calculate the energy that the wire radiates in 10 minutes. Suppose the surface temperature of the Sun were about 12,000K, rather than 6000K. a. How much more thermal radiation would the Sun emit? b. What would happen to the Sun's wavelength of peak emission? c. Do you think it would still be possible to have life on Earth? Explain /A The energy radiated by a black body at 2300K is found to have the maximum at a wavelength 1260 nm, its emissive power being 8000W/m2. When the body is cooled to a temperature T K, the emissive power is found to decrease to 500W/m2. Find : (i) the temperature T k (ii) the wave length at which intensity of emission in maximum at the Te / Black body becomes yellow with λ…arrow_forwardThe spectrum of a typical star shows absorption lines at different wavelengths than their laboratory values. If the observed wavelength is greater than its laboratory value of 656.3 nm, one can conclude that ... A. The separation between Earth and the star is decreasing. B. The separation between Earth and the star is increasing. O C. The separation between Earth and the star is unchanging D. No conclusion is possible.arrow_forward
