Explain convergent and divergent
Answers
Answer:
If the aforementioned limit fails to exist, the very same series diverges. It's denoted as an infinite sum whether convergent ordivergent. The partial sums in equation 2 are geometric sums, and this is because the underlying terms in the sums form a geometric sequence
Answer:
Convergence !!
The beam is used when we want to concentrate light at a point. This type of beam is used by doctors to control light on teeth, ears, eyes etc .
It is also used in solar water heaters and the other devices.
[Seee in attachment figure(a)]
Divergence !!
This beam is used when we want to spread light from a point source of light.
This type of beam is used in streetlight, Vehicles , etc.
[See in attachment figure (b)]
Extra !! :---------------
Convergence And Divergence !!
Both the beams have practical utility and therefore, we need devices to produce coverging and diverging beams . But a plane mirror reflects a parallel beam of light.
Secondly, A plane mirror produces an image which is of the same size as that of the object.
But there are a number of applications where we need images of bigger or smaller size as compared to the size of objects.
We need Spherical And Parabolic mirrors for these purposes.
