Sorry. Since I am a secondary school student, I am unfamiliar with this question. Now I undserstand that the equation on the exam was wrong, thank you very much.berkeman said:Welcome to the PF.
How would you approach the problem? We need you to show your efforts before we can offer tutorial assistance.
I find out the equation was incorrect, thank you and have a good day.haruspex said:It would help if you could indicate what part is not making sense to you.
Do you understand that the received power is FA sin(θ)?
Do you understand that if the absolute temperature is T then the emitted power is 2AσT4?
Do you understand that the two will be equal in steady state?
In what way? It looks right to me. Who says it is wrong?Leo Liu said:I find out the equation was incorrect, thank you and have a good day.

Ah, that equation. I thought you meant the one in the answer.Leo Liu said:
Radiation is used in medical treatments, such as radiation therapy, to kill cancer cells and shrink tumors. It is also used in imaging techniques, like X-rays and CT scans, to diagnose and monitor diseases.
Aside from medical uses, radiation also has numerous industrial, agricultural, and scientific applications. It is used in food processing, sterilization, and power generation. It is also used in scientific research to study the structure of materials and the universe.
High levels of radiation can be harmful to humans, causing damage to cells and DNA. However, low levels of radiation are a natural part of our environment and are not harmful. Proper safety measures and regulations are in place to protect individuals from excessive exposure to radiation.
Radiation can have both positive and negative effects on the environment. It can be harmful to plants and animals if levels are too high, but it can also be used to control pests and diseases in agriculture. Radiation is also used in environmental monitoring to study air, water, and soil quality.
The risk of exposure to radiation depends on various factors such as the type of radiation, duration of exposure, and distance from the source. Acute high-level exposure can cause immediate health effects, while long-term exposure to low levels of radiation may increase the risk of cancer. However, the risks can be minimized with proper safety measures and monitoring.
