Following up on Exercise 29.27 calculate the energy of a typical photon. Assume for this approximate calculation that each photon has the wavelength calculated in Exercise 29.25. The energy of a photon is given by E=hc , where h is Planck’s constant and is equal to 6.6261034Js , c is the speed of light in m/s, and ? is the wavelength in m.
The greenhouse effect can be explained easily if you understand the laws of blackbody radiation. A greenhouse gas blocks the transmission of infrared light. Given that the incoming light to Earth is sunlight with a characteristic temperature of 5800 K (which peaks in the visible part of the spectrum) and the outgoing light from Earth has a characteristic temperature of about 300 K (which peaks in the infrared part of the spectrum), explain how greenhouse gases cause Earth to warm up. As part of your answer, discuss that greenhouse gases block both incoming and outgoing infrared light. Explain why these two effects don’t simply cancel each other, leading to no net temperature change.
Thinking about the topics in this chapter, here is an Earth analogy. In big cities, you can see much farther on days without smog. Why?
What do we mean by the ground state of an atom? what do we mean by the excited state of an atom?
The explosive energy of a ton of TNT is 4.184*109 Joules, according to Google. A megaton of TNT is a million times that. According to Wikipedia, the Tsar Bomba (Links to an external site.) was the most powerful thermonuclear weapon ever exploded, at 50 megatons of TNT. (For comparison, the explosive energy of WWII nuclear bombs was about 20 kilotons.) Suppose one kg of antimatter came into contact with matter. How would the explosive energy compare with the explosive energy of the Tsar Bomba? (c = 3 * 108 m/s) Group of answer choices 1.There is no way to compare the two. 2.The kg of antimatter would produce at least a hundred times more energy. 3.The Tsar Bomba produced at least a hundred times more energy than the kg of antimatter. 4. They would be approximately the same.
