Question

If log a, log b, log c are in A.P then a, b, c are in which progression ?

Answer 1

hey mate here is ur answer

If log a, log b, log c are in AP

then by property if AP

2b=a+c

2log b=log a+log c

log b²=log ac

cancelling log

b²=ac-----[G.P.]

hence they are in geometric progression

hope it helps.

Answer 2

Answer:

In geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system. A paraxial ray is a ray which makes a small angle to the optical axis of the system, and lies close to the axis throughout the system.
