Most Important Questions of Light Physics | Class 10th Science Board Wake Up with Ashu Sir

[@anushkameenashorts7791]

I am 2023-24 batch student of class 10th...and i am in 11th now.. I got 94% in class 10th by science and fun... And i randomly get this video on my feed and i feel very nostalgic.. And got goosebumps while watching this again.. And getting thoughts of that time when i was preparing for boards.. Such a great.. Stressful and memorable experience... Thank uu ashu sir and his whole team

My notes (ignore it) 12:50 non uniformly speed change hoegi 20:00 Calc mistake 29:10 avoid silky mistake yaar and read the q carefully. (Yes I will) 52:54 power 0 means plane mirror

1:28:53 We can also take 1/u=0.5cm and 1/v=1cm from the graph Then we would get F=1m Clear it!!

No my friend.... There are two different focus given

[@SHIJOOO]

Yes we can , its a mcq so obv we can do

The correct answer is option B i.e. f(n+1)

'u' ko minus liye ki plus mee?

[@sundram1949]

​@@Firedfreakstart se hi 'u' ko minus (negative) me Lena.. pata nhi kyu but ek dusre question me bhi Maine 'u' ko shuru se positive liya tha to galat aaya answer..

[@vinayakpandey5912]

Sir ne Jo ques homework Diya tha..... If you know then please explain me !

[@sundram1949]

​@@vinayakpandey5912In the question magnification is given as 1/n.. Take U as positive for now only,, -v/(u) = Hi/Ho.. -v/u = 1/n,, v = -u/n.. 1/f = 1/v + 1/u,, Putting v = -u/n,,, 1/u = 1/v - 1/f → -n/u - 1/f,, -fn-u/fu = 1/u,, do cross multiplication,, fu/u = -fn-u,,, f = -fn-u,, change side,, u = -fn-f = -f(n+1),, -u = f(n+1) { u is always negative}.. Hence, B is correct { (n+1)f }

Tip :- Always take 'u' as negative from the very start or you might stuck..
