Why is it impossible for a gas composed of atoms that all have their electrons in the ground state to produce an
emission line?
A 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?
A blue-hot star is about twice as hot as a red-hot star. But the temperatures of the gases in advertising signs are about the same, whether they emit red or blue light. What is your explanation?

- Question 3 Treat the surface of the sun as a perfect blackbody at a temperature of 5800K. According to Planck's distribution law, what is the ratio of the intensity of the radiation emitted by the sun in the high-energy end of the visible spectrum (around 380nm) compared to that emitted in the low-energy end (around 680nm)? Question 4 Treat the surface of the sun as a perfect blackbody at a temperature of 580OK. According to Planck's distribution law. how many photons are emitted by the sun in the high-energy end of the visible spectrum (around 380nm) for every photon emitted in the low-energy end (around 680nm)?arrow_forwardState whether it is true that “the A spectrum is AM0 and the B spectrum is AM1.5”. Explain why B is weaker than A across the whole wavelength range. Show how you estimate the surface temperature of the Sun using the given spectrum.arrow_forwardWhich of the following statements are TRUE about the Sun's spectrum, which is shown in this image? Brightness 2.5 3.5 0 Jay 200 Sun's Spectrum vs. Thermal Radiator of a single temperature T = 5777 K peak spectrum of Sun spectrum of T=5777 K blackbody emission spectrum (continuum) absorption lines 400 600 800 1000 1200 1400 1600 Wavelength (nanometres) 1800 2000 The spectrum shows that the Sun emits light of all colors equally, which is why we see it as white. The spectrum shows the presence of many sunspots. The peaks and valleys in the black line reveal the chemical composition of the Sun. The spectrum shows absorption features (spectral lines). The spectrum represents a perfect blackbody.arrow_forward
