Answer #1

according to wein's displacement law, when the temperature of a blackbody radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. When the maximum is evaluated from the Planck radiation formula, the product of the peak wavelength and the temperature is found to be a constant.

where b is the displacement constant having a value= m.K

so the answer is true

Stars emit radiation whose spectrum is very similar to that of a blackbody. Imagine two stars identical in size, each of which is at the same distance from us. One of the stars appears reddish in color, while the other one looks distinctly bluish. Based on this information, what can you say about the relative temperatures of the two stars? Which is the hotter? The relative temperature of a star that is red in color is higher than that of...

The wavelength of peak emission from any star is related to the temperature of its photosphere (i.e., the emitting surface) by Wien’s Law, given by λ = 2,900/T, where λ is the wavelength in micrometers (1 µm = 10-6 m), and T is the temperature of the star in Kelvin (see textbook’s figure 3.27 for help). Answer the following questions using the above equation. 2.1. The most massive star ever observed is a Wolf-Rayet type-star, named R136a1. It is so...

Is more energy released by positron emission or electron capture? I read online that "electron capture is more economical in energy than positron emission, its competitor. The creation of a positron requires 511 keV, the mass energy of the positron. If the energy released in the decay is smaller than 511 keV, the emission of a positron (beta-plus decay) is not allowed. Below this energy threshold, electron capture becomes the only process available to reduce an excess of protons." Which...
