- 6. What is the temperature of an object if the peak wavelength of its blackbody spectrum is 1200 micrometers? a. 2.4 K b. 25 K С. 322 К d. 833 K e. None of these CS Scanned with CamScanner2. A photon is emitted from a hydrogen atom that undergoes an electronic transition from the state n=3 to the state n =2. Calculate (a) the energy, (b) the wavelength, and (c) the frequency of the emitted photon.True or false? 1. Collisions in denser phases lead to shorter lifetimes and broader peaks. 2. The Doppler effect can be minimized by increasing the temperature. 3. Resolving power increases with increasing D1.
- 1. A star such as our Sun will eventually evolve to a “red giant” star and then to a “white dwarf” star. A typical white dwarf is approximately the size of Earth, and its surfacetemperature is about 2.5×10 3K. A typical red giant has a surface temperature of 3.0×104 K and a radius ~100,000 times larger than that of a white dwarf.a) What is the average radiated power per unit area by each of these types of stars?b) What is the ratio of total power radiated from the white dwarf over the power of the red giant2. The emission spectrum for sodium below shows two bright lines at frequency 1(f ) and frequency 2(f ). The difference in energy between Frequency 1 and Frequency 2 can be determined with what formula using the frequencies (f and f ) and Planck’s constant (h)? answer choices are in the images attached!!4.-The radius of the Sun is 6.96 × 108 m, and its total emitted energy is 3.85 × 1026 W.a) Assuming that the surface of the Sun radiates as if it were a blackbody, calculate its surface temperature.b) Using the result of part a), determine λmax for the Sun.
