Sign conventions for mirror & lenses (Hindi) | Light | Physics | Khan Academy

Let's explore the sign conventions (rules to assign +ve and -ve values) we use for mirrors and lenses.
These rules are called Cartesian sign conventions
Practice and master this concept here:

[@manjiltheeng190]

I'm from Nepal 🇳🇵🇳🇵and in our Nepali writers physics book the sign convention rule is exactly different from your sign convention rule 😁😆

[@enterchannelname21]

True bro . It's totally different . I am back to my book . Lmao 😂

[@enterchannelname21]

But i will watch this too . Why don't we increase our knowledge.

[@bibekbohara8481]

Yes bro which is true can you expain it

[@iwantcheesecake63]

Wait what how

[@learnersseries1167]

There are two sign convensions used in optics:
1) conventional
2)cartesian
In nepal conversational convensions are used but in india cartesian convensions are use.....both are true

[@itsaditya7146]

Thanks sir...U have cleared my all dought.....

[@chumkidas5715]

Very useful video .I solve my problem by seeing this video.thank u so much sir .Make more video about physics formula related.

[@simranbintjavaid9865]

I am confused in example 2 plz reply me😢😢

[@Yusrayousuf411]

I am also

[@deepakkandpal9303]

I am also

[@ShivamGupta-pq3gx]

Don't get confused watch carefully it's Convex mirror not concave .
Hence U =-7 because it's outside the mirror not inside
V=+1 because it is inside the mirror
F= +2 it is also inside the mirror
Basically confusion because you are assuming it as concave but it is a convex mirror.

[@neelamsingh4429]

It's simple enough yrr..jusz try again n u can do it
