Thank uh soo much sir its really very mcuh helpful video
Sir I have a big big doubt that focal length is positive or negative in concave mirror, concave lens, convex mirror, convex lens
Can't appreciate your true hardworking in words love cbse guidance
Thankyou so much sir your explanation clears all my doubt😊😊
Really really very influenced by your teaching sir ❤❤
Do working hard for us ❤
Heads off to you sir ☺️💗

Sir aap plz ek baar paper se pehle last revision karva diya kro
thank you sir videos helped me alot
Sirrr... Hats off to you. You're really a great teacher.❤
sir magnification ka formula kya h ?M=v'/u OR M=h'/h=v'/u
humhe konsa formula use krna h???and dono formula se kya same ans aayega??
yes sir plz reply
yes sir plzzz
kisi ko pta h??🤦♀️
Ha dono formule se same answer hi aayega. h' is size of image isko hum i bhi likh sakte hain and h is size of object isko hum o bhi likh sakte h. Then,
m(magnification) = -v/u
m= i/o
m= h'/h
i/o = -v/u
Ye saare formule use hote h or same answer aata h. Agar aapko size of image and object dono diye h or aapko v ya u me se kuch nikalna h toh aap i/o = -v/u use kr sakte ho.
Hope you understand and if any doubt ask☺️
