Question

will the focal lengths of different lengths of two identical lenses with different refractive indices same. explain briefly?..''

Answer 1

heya !!


>>> will the focal lengths of different lengths of two identical lenses with different refractive indices same???


here's your answer:

________________________________________________________________________


>>THE FOCAL LENGTHS OF THOSE IDENTICAL LENSES WILL BE DIFFERENT AND NOT SAME, IF THEIR REFRACTIVE INDEX VARIES BECAUSE THE FOCAL LENGTH OF A LENS DEPENDS ENTIRELY ON THE REFRACTIVE INDEX OF IT,
>>AND IF IT CHANGES AUTOMATICALLY THE FOCAL LENGTH CHANGES , EVEN IF THE LENSES ARE IDENTICAL.

Answer 2

HIi DEAR FRND.
===============


THE LWNTH OF THE
TWO DIFFERENT IDENTICAL LENSES ARE NOT SAME ..

LARGE LENS OF FOCAL LENGTH LESS Light THAN SMALL FOCAL LENGTH LENS. .

THE LARGER DIFFERENCE BETWEEN THE REFRACTIVE INDEX OF THE LENS AND THE REFRACTIVE INDEX OF THE SURROUNDING AIRr, THE MORE LIGHT WILL BE TITLED BY THE ACTION OF THE LENS.

FOCAL LENGTH...
THE LARGER THE FOCAL LENGTH, THE LOWER THE EFFECT OF THE LENS IS ON THE WAY TO THE LIGHT....

THANK YOU..
