yes

What is the prove of this formula ???

Sir ...i guess magnification is represented by small 'm' not capital. ...

Sir during derivation we got hi/ho = v/u sir.

[@prabhsekhon278]

If m= 1 then image has same size of the object ...??????????

[@Indianexplorer47]

Sir reason for this already present minus sign

[@Anshu_18.]

Sir ne derivation me v/u btaya tha or is me v/u bta rahe h

[@padakukida5842]

Sir I had a doubt.. In the mirror derivation u said that hi/ho is v/u and now u r saying its -v/u..? Waiting for ur quick response, Thank You! Regards, #AStudent

[@knowledgetime4306]

-v/u real image ke liye hota aur v/u virtual ke liye

[@Isitamazing]

Sir but in the mirror formula we know that hî/hô=v/u

[@princeyadav8710]

Sir in Derivation of Mirror formula You derived hi/ho= v/u So how here it became -v/u Plz answer this!

[@raviupa6050]

Because jo Image form hogi wo diminished rahenge mtlb small rahenge than the object.🔥

[@princeyadav8710]

@@raviupa6050 Then how is that related to chenge in sign

[@princeyadav8710]

@@raviupa6050 According to sign convention + and - just tell the position!

[@raviupa6050]

@@princeyadav8710 Bro Dekho mai batata hu ke ye kha se aya hai Listen carefully. We know that We take sign of height of object and image in order of principal axis means Jo principal axis ke upar hoga wo positive and jo principal axis ke neeche hoga wo negative only in terms of height of object and image. So agar hmmh diagram me dekhe similar triangle wale me jo mirror derivation hai usme object image is positive and image formed is negative which means - Hi/Ho ALSO distance of object is taken from pole of mirror this is important from pole of mirror .So distance of object I.e U is negative and also distance of image i.e V is also negative which can be written as -V/-U minus minus gets cancel therefore we have V/U . Now compare ratios of sides . - Hi/Ho= V/U Hi/Ho= -V/U
