I obviously still have a long way to go to become like yourself and others on this site, but thanks:angel:

this was possibly the dumbest question i asked on here, at that time i had just started learning physics and had very wrong intuition/assumptions lol, i mean i was literally calling the "restoring force" reaction force as if action and reaction forces act on the same body o0). i also thought...

Oh i missed that sorry just noticed. Anyways thankyou for helping me understand it. ☺

Yes, since you specifically asked in post #2 about sunset so that's what I replied to..

The sun is physically on the lower right but we see it on the upper right right during sunset...its virtual image is what we see and in our pov it stays for longer..

The upper image of the sun on the right

Yes I can stil see the upper edge after it is geometrically lined up with the horizon. So like the day starts earlier and ends later for us observers? Hence the time interval is longer?

I honestly do not understand which one is referring to which one, the optical length states that the time interval between the instant when the top of the sun is just "visibly observed" above the horizon to the instant at which the top of the sun just disappears below the horizon. The sun that...

oh no you're good, i wouldn't have guessed that its not your first language, maybe because english is not my first language aswell and by my standards yours is pretty solid :cool:

As far as I remember I haven't gone beyond 4 tries. Wish I had played the games after signing up so I could have saved my stats

So like say n1d1 is the common difference after which another common term is seen. And n2d2 is the common difference in the second ap after which this same common term is seen so A+n1d1=A+n2d2 n1d1=n2d2 does this imply that n1d1 is the LCM(D1,D2)...?

Oh i didn't think of this.......

If i take any two APs say a=1; d=5; 1,6,11,16,21,26,31,36,41,46,51......1+(n-1)5. say a=2; d=3; 2,5,8,11,14,17,20,23,26,29,32,35,38,41......2+(n-1)3. If i pick out the common terms here, I get an AP again o common difference 15. 11,26,41....11+(n-1)15 How can i prove that the common terms of...

Thanks a lot for the help. Is there a way to guess when to use this approximation? In this question i didn't know if the image formed by the objective was close to the eyepiece or not, or if the object was kept at the focus of the objective, In the official prescribed textbook tube length is...
