A thin lens, made of a material of refractive index g, has T. [f the lens
medium of refractive index 'n' (n g), Obtain an enprcssion for the change in the focal length
Use the result to show that the fi_wal length of a lens of the glass W g 8 ) becomes
time'
focal length in air, When it is placed in Water = g happens Whed n > g? Explain
appropriate ray diagram.
Is current density, a Vector or a scalar quantity? Deduce the relation hetq•ccn current density arÆ
difference across a current-carrying conductor of length L area of cross-section A, and number
electrons n. HOW docs the current density, in aconductor vary With
(a) increase in potential gradient?
(b) increase in temperature?
(C) increase in length'?
(d) increase in area of cross-section?
(Assume that the other factors remain constant in each ease:)
1/f = (nu - 1) [1/R1 - 1/R2] ----------- equation 1 i missed this step

G.v Sankirtana answered this
f1 = (nu-1).f/nu - n is equation 3 and delta f = R1R2/R1-R2 [n/nu-n - 1/nu - 1] this is equation 4
that line which is written with pencil and not clear is from equation 2 sorry if the image was blur :")
hope this helps :)
hope this picture is clear for u
hope this is the clear one :)
