The teacher in this video, way of explanation and the explanations themselves, everything is just amazing. I strongly suggest Khan Academy Management, to promote and support this teacher further. I am a physics teacher myself and I liked the videos by this teacher a lot.

[@tanmaymeshram8343]

SIR WHY POWER OF LENS IS EQUALS TO THE RECIPROCAL OF ITS FOCAL LENGTH ... SIR PLZ ANSWER SOON AND IF ANYONE KNOWS ABOUT PLZ REPLY WITH EXPLAINATION

[@rahulnandi3606]

See the previous chapter of physics i.e. LIGHT

[@missionworldtour5709]

It is a formula

[@sanjaykumaryadav2438]

Aap 12 class me ao .......eeska proof v milega..

[@adityamishra2027]

Because power of lens is inversely proportional to focal length and constant of proportionality is 1

[@SkSk-so8nm]

Power is defined as 1/f . Scientist have named the quantity 1/f as power

[@mr.kd.waghmare2667]

Sir very nice . Now I clearly understand

Simply in the case of myopia (near - sightedness) , Defective far point = Focal length of the corrective lens For ex - here , f of the corrective lens = - 200 cm (- ve for a concave lens)
