Step 1: Use Wien's displacement law equation: λ_max * T = b, where b is the Wien's constant (2.8

Question

2. The peak in the spectral distribution curve for radiation from "radio stars" occurs in the microwave region of the electromagnetic spectrum (~10?² m). Assuming that this radiation originates mainly from thermal emission, determine the approximate surface temperature of such stars. 3. What is the peak wavelength radiated by a blackbody at room temperature (~300 K)? Is this wavelength visible to the eye? 4. a. Calculate the total power radiated per unit area by an incandescent lamp filament at 2700 K. b. Determine the surface area of the filament if the lamp radiates 100 W (mostly as infrared radiation). 5. Use Balmer's formula to calculate the wavelengths of the first three spectral lines of the Balmer series. 6. Compute the energy of a photon of red light (? = 650 nm) and a photon of ultraviolet light (? = 400 nm). Why is ultraviolet light potentially more harmful to the skin than red light? 7.
