Question

A thin lens has a focal length of, -25cm. what is the power of the lens​

Answer 1

hola mate THIS is your answer

GIVEN

focal length of a thin lens= -25 cm

power of lens=?

WE KNOW THAT

P=100/f(cm)

=100/25

=4

NOTE: as - is consider for myopia

power of given thin lens = 4 diopters

Answer 2

Answer:

we know that the relation between Focal length and Power

p = 1/f

Here is given that, to

f = –25

then the Power will be

p = 1/-25

p = –0.04 ««««Ans.
