Guys isme ek topic chut gaya
Let me tell you that
About a Principal focus
Of concave that:
AFTER REFLECTION WHEN THE LIGHT RAYS CONVERGE AT A POINT ON A FOCUS THAT POINT IS KNOWN AS PRINCIPAL FOCUS OF CONCAVE MIRROR.
FOR CONVEX:
WHEN THE LIGHT AFTER REFLECTION APPEARS TO COME OR APPEARES TO
CONVERGE AT THE POINT ON THE VIRTUAL FOCUS
THAT IS KNOW AS PRINCIPAL FOCUS OF CONVEX MIRROR 😄

respected sir as this is an amazing series and very helpful but with due respect I found a mistake in 5:49-5:53 where u told that silver coating will be on the backward side of convex mirror but the actual silver coating will be on the same side as the concave mirror
Nope bro sir said that the backward side of the convex mirror is polished. The diagram given there for convex mirror is wrong the actual polish side all time is backward of any mirror

Sir can you gave me the answer of the question....
18. Mentioned below are laws of refraction. There is a mistake in these laws. Find it.
A (i) The incident ray, refracted ray and normal to the surface separating two medias at the point of incidence, all lie in the same plane. (0)
(ii) The ratio of sine angle of incidence to the sine angle of refraction remains constant.
(A) In (i), instead of same plane it should be different planes.
(B) In (ii) the ratio remains constant only in certain situations.
(C) In (ii) the ratio is available in all situations.
(D) In (i) it should be 'point of refraction' rather than 'point of incidence'.
