Hello, everyone.
On physics Olympiad in our country I get a interesting example... But, I didn't know how to solve it.
Can you tell me how?
It is known that the Moon when it is full has the apparent magnitude of approximately -12 mag and the Sun during the day has the apparent magnitude of -27 mag. Try to figure out what is the apparent magnitude of the Moon directly before a solar eclipse, if you know that the albedo of the Earth is approximately 0.36 and the albedo of the Moon 0.12. Presume that light after reflection disperes the same way on the surface of both the Moon and Earth.
Hmm... I know Pogson's equation. So I know the I_Moon/I_Sun thanks for it. I also know, how looks position of solar eclipse. However, this is everything. I know what is albedo, ok, but any equation between magnitude and albedo? No, really no :-(
Please, give me a advice.
Thank you very much and sorry for my bad English :-)
