Homework Statement
Calculate the flux at point P located at a distance r from the centre of a sphere with uniform brightness, B. Idem for an infinite plane with the same brightness B. And the same for a square surface with side L.
Relevant Equations
N/A
Hi! I’m really struggling to solve the last part of this problem, from where it says “Idem for an infinite plane with the same brightness B. And the same for a square surface with side L.”.

Could anyone please help or point me in the right direction? Thank you so much in advance!

1. What is the source of radiation in astronomy?

The primary source of radiation in astronomy is the Sun. Other sources include stars, galaxies, and cosmic rays from outside the solar system.

2. How does radiation affect objects in space?

Radiation can have various effects on objects in space, depending on the type and intensity of the radiation. It can cause heating, ionization, and damage to DNA and other molecules.

3. What is the difference between ionizing and non-ionizing radiation?

Ionizing radiation has enough energy to remove electrons from atoms, while non-ionizing radiation does not. This difference is important because ionizing radiation can cause more damage to living cells and DNA.

4. How do astronomers protect themselves from radiation?

Astronomers use various methods to protect themselves from radiation, such as wearing protective gear, using shielding materials, and limiting exposure time. They also use remote observation techniques to avoid direct exposure to high levels of radiation.

5. How can radiation affect space exploration missions?

Radiation can pose a significant risk to astronauts and equipment during space exploration missions. It can cause damage to electronic systems, increase the risk of cancer and other health issues, and impact the success of the mission. Therefore, proper shielding and monitoring of radiation levels are crucial for the safety and success of space missions.
