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...

A lot of blackbody irradiation emanates from the surface of the earth. Recall that light energy (and energy from any region of the electromagnetic spectrum) is quantized. The energy of a photon can be calculated as follows: E = hν = hcλ where h is the Planck constant (6.626×10−34 J⋅s), and c represents the speed of light (2.998×108 m/s). Calculate the energy (in joules) of each photon that is emitted from a patch of ground that is at 32 ∘C....
