Optics
Optics covers the properties of light and its interactions with materials including refraction and polarization. In particular it covers the behavior of optical lenses.

Should you use fiber optic lighting?
Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. This saves your provider (cable TV, Internet) and you money. Thinner - Optical fibers can be drawn to smaller diameters than copper wire. Higher carrying capacity - Because optical fibers are thinner than copper wires, more fibers can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same cable or more channels to come through the cable into your cable TV box. Less signal degradation - The loss of signal in optical fiber is less than in copper wire. Light signals - Unlike electrical signals in copper wires, light signals from one fiber do not interfere with those of other fibers in the same cable. This means clearer phone conversations or TV reception. Low power - Because signals in optical fibers degrade less, lower-power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires. Again, this saves your provider and you money. Digital signals - Optical fibers are ideally suited for carrying digital information, which is especially useful in computer networks. Non-flammable - Because no electricity is passed through optical fibers, there is no fire hazard. Lightweight - An optical cable weighs less than a comparable copper wire cable. Fiber-optic cables take up less space in the ground. Flexible - Because fiber optics are so flexible and can transmit and receive light, they are used in many flexible digital cameras for the following purposes:
- Medical imaging - in bronchoscopes, endoscopes, laparoscopes
- Mechanical imaging - inspecting mechanical welds in pipes and engines (in airplanes, rockets, space shuttles, cars)
- Plumbing - to inspect sewer lines
Because of these advantages, you see fiber optics in many industries, most notably telecommunications and computer networks. For example, if you telephone Europe from the United States (or vice versa) and the signal is bounced off a communications satellite, you often hear an echo on the line. But with transatlantic fiber-optic cables, you have a direct connection with no echoes.
How and when is the image inverted?
Whenever a real image is formed by a real object,the image is always inverted.
for eg when light rays from infinity falls on convex lens it forms a real and inverted image at focal plane.
What is the best scope for a Beeman C1?
The best scope is one you can afford. Scopes very in price. So here are two I suggest
Leapers 3-9X32 AO
Browning 3-9X40 AO Duplex Reticle
Try Pyramydair online to see various scopes.
How does a mirror reflects right hand into left hand and what this effect is called?
Lateral inversion
What is the purpose of Bushnell Yardage Pro Sport 450?
The Bushnell Yardage Pro Sport 450 is a laser range finder used to measure distances between pins, nearby hazards, and other objects. It is mainly used in the sport of golf.
Why incident ray and emergent ray are parallel to each other in the refraction of light?
Because both incident ray and emergent ray have same slope.
The suspended material is rock-flour - very fine particles arising from the grinding action of rock-on-rock under the moving glacier.
Do not drink it!
Does all the light enter the glass block in refraction?
No. A part of the total may get partially reflected.
same problem dude..
Compare satellite and fiber optics communication?
Fiber optics is quicker and has higher bandwidth but for long distances requires more infrastructure (but it is on the planet so is more easily repaired).
Satellite communications is slower with lower bandwidth and noticeable delays, the long range capability is greater but parts of the infrastructure (the satellites) are very expensive to replace and repair.
What happens when you make a rainbow with the help of a glass of water and sunlight?
The sunlight hits the glass of water and then the light disperses out as a spectrum of colour (rainbow). This is because sunlight is white light and white light contains the 7 colours of the rainbow. When it hits the glass the colours refract and disperse out as the spectrum of colours, which we see as a rainbow.
What did you observe with the indices of refraction of the colors of light in the acrylic prism?
why did you observe with indices of refraction of the colors of light in the acrylic prism
Who is the father fiber optics?
It wasn't a one man effort, inventing fiber optics. Works were inspired by John Tyndall who first discovered light can travel an irregular path through glass. Alexander Graham Bell later contributed. Heinrich Lamm in 1930 put the first fiber optic cable together stranding cable together and sending a signal across the wire. There were many other people who helped improve it over the year.
Al Gore is not the father of Fiber Optic cables, in case you were wondering.
Why is study of trigonometry important in optics?
The sine ratio plays an important part in the refraction of light at the interface of two media through which the light travels - such as the interface between air and the glass of a lens.
my answer is 5
How do angle of reflection and angle of incidence relate?
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. The angle of incidence is equal to the angle of reflection because the light ray selects the shortest path to reach the destination. This behavior of light is known as Fermat’s principle.
its is the eyes
Why is sin used in the refraction of light?
Light follows the Law of Sines in refraction and reflection'
sin(I)/VI = sin(T)/VT=sin(R)=VI.
Can you see pictures of refraction light?
Yes you can. The album cover of Pink Floyd's "Dark Side of the Moon" is a good example.
