Calculating the Sun's Luminosity: The Equation Revealed

AI Thread Summary
To calculate the Sun's luminosity based on the energy received by Earth, the relevant equation involves the inverse square law of light and the distance from the Sun. Luminosity is a measure of the total amount of energy emitted by a star per unit time. It directly relates to energy output, as higher luminosity indicates more energy being radiated. The original poster initially sought help but later figured out the equation independently. Understanding luminosity is crucial for astrophysics and studying stellar properties.

[SOLVED] luminosity of the sun

What equation do you use to figure out the luminosity of the Sun if you are given the amount of energy the Earth receives from it?
 
Physics news on Phys.org
Can you please post the whole problem and whatever work you have done. Remember you must show some work to get help on these forums. You don't necessarily need calculations, but you need to show that you have put some thought into the problem. Can you answer the following:

What is luminosity a measure of?

How does luminosity relate to energy?
 
Ok sorry. I actually just wanted to know the equation, but i figured it out. thanks anyway
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
