Why is a small critical angle desirable for optical fibers What problems could be caused if the critical we're increased?

because a smaller critical angle means that it is easier for total internal reflection to occur, which is the desirable quality in an optical fibre.

How do optical isomers rotate plane of plane polarised light?
REFER : optical rotatory dispersion
What is the cardinal point of optical system?
The points on the optical axis OO' (see Figure 1) of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.
What does the angle of parallax determine?
Accuracy of readings of e.g. meters and certain optical instruments. Parallax is also used in astronomy for calculating distances to(astronmically)far-away objects.
What is bak-4 prism?
BAK-4 prisms are the best; they are made of superior optical glass that produces clearer images. BAK-4 prisms show a truer round, which translates to better light transmission and edge-to-edge sharpness. These are what you want in your binoculars.
How many images are formed if two parallel mirrors are put facing each other?
Very many. The glass of real mirrors is not perfectly clear and the reflective coating of real mirrors is not perfectly reflective so the images dim. But is not hard to get 50 or more spots of light when shining a laser pointer into such a mirror configuration. ------------------------------------------------------------ Edit:Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
The LEAST desirable location for an optical telescope is likely to be?
in a larqe city.
Does optical insurance cover disposable contact lenses?
If you were to purchase optical insurance, you would have to pay an increased rate for a preexisting condition. However, the optical insurance would cover the cost of of the lenses.
What is used to describe the light gathering or light collecting ability of an optical fiber?
a. Critical angle
What are optical output devices?
if u multiply optical x input and input x optical then u will receive the input optical for ur result and this will be ur optical input. my answer is correct and it will work no matter what. if u have any problems go ask someone who cares. xx

What tools would help you determine the source of either of these problems?
optical time domain reflectometer
What type of zoom results in increased magnification without a change in image quality?
If I understand your question correctly then it would be an optical zoon
Is it the eye or the brain that sees the optical illusion?
It is the brain that has problems in interpreting apparently contradictory inputs from the eye.
What has the author Helmut Dosch written?
Helmut Dosch has written: 'Critical phenomena at surfaces and interfaces' -- subject(s): Critical phenomena (Physics), Grazing incidence, Neutrons, Optical properties, Scattering, Surfaces (Physics), X-rays
What is a circular polarized filter?
It provides high quality optical glass for increased clarity and limits reflection from nonmetallic surfaces and picture washout.
How has using optical fibers made an impact of survival rate on surgical problems?
Optical fibers make an impact because it needs to be thick enough so the surgery van be easier which controls the rate
