Why is gold used as the reflective surface of some solar panels?
A thin layer of gold that is transparent to visible light but reflective to infrared light is used to keep the temperature of the panels down. This is important in space where the atmosphere does not block solar infrared light, but not needed on the surface of earth.
The transmission of a certain type of data by means of light through transparent fibres.
What is the speed of light in a material with an index of refraction of 3?
It would be 100,000,000 metres per second.
IMAGE! image means that it is a image of something or some one and it has been put into an image.
Why a light ray changes its path during refraction?
Light does not travel at 3.0 x 108 m/s unless it is in a vacuum. In air, water, glass and diamonds it travels more slowly and bends as it changes from one medium to another. Diamonds slow the light a great deal. That's why the can appear to sparkle as the light bounces around inside.
Light rays change path during refraction due to the change in density of the material. This can most easily be seen when looking at a stick sitting in water. The stick appears to bend.
As light travels in air it can travel faster than it can travel in water. When the ray of light hits the water at an angle it tends to bend down towards the perpendicular line to the surface of the water.
If light travels from a more dense to a less dense medium its speed will increase. The light beam, instead of traveling in a straight line as it exits the denser medium will bend away from the perpendicular.

What are the advantages of using a magnifying glass that is foldable with bult in light?
When the object under observation is well lit, then you can view it more clearly. Some objects which you want to observe under magnifying glass, may not have been well lit naturally. Magnifying glass with lights will help look at it more clearly.
How would this indices of refraction account for the arrangement of color?

1FO1 is a internet service provider, the Brand name stands for "1 Fiber Optics 1", some say it stands for "1 Follow On 1" but considering 1FO1 is a network operator I would say the name stands for number 1 Fiber optics network. 1fo1 is also an abbreviation for a mrna.
Answer: A sheet that is optically anisotropic.
Answer: "Film" means that it is a thin layer "polarizing" means that it polarizes light that goes through it. For example, if you shine unpolarized light on it, light will get out on the other side - polarized in a certain orientation.
Name two career opportunities in the field of optics?
Two career opportunities in the field of optics are optical engineer and optometrist. Optical engineers design and develop various optical components and systems, while optometrists focus on diagnosing and treating vision problems. Both careers require a strong understanding of optics principles and technologies.
What are the differences between the glass optic and plastic optic for use as fiber optics?
Glass is most often used for long range and high speed because it transmit light better.
Plastic is cheaper but has got certain limits both to speed and range(as in distance).
Plastic is being developed a lot and recent types of plastic material has got near glass qualities.

Why concave mirror is used for shaving?
Some people use concave mirror because when a man stands between the principal focus and pole of a concave mirror,he sees an enlarged,erect and virtual image of his face.this is the reason why a concave mirror of large focal length is used for shaving.
concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting.
because when a man stands between the pricipal focus and pole of a concave mirror , he sees enlarged ,erect and virtual image of his face .that is why concave mirror of large focal length is used for shaving
What questions does a ray diagram answer?
A ray diagram helps to answer questions about the image formed by a lens or mirror, including the size, orientation, and location of the image relative to the object. It also indicates how rays of light interact with the optical device to create the final image.
What are some advantages of free space optics?
Some advantages of free space optics are lower costs, no fiber optics cables to run and no expensive rooftop layouts and installations. Also, the system may be upgraded in an easy manner without an RF license.
How does the refraction of light as it passes from air into water cause optical illusion?
I'm only twelve in sixth grade believe it has something to do with reflecting and bouncing off of certain thing's. Sorry I don't have any more info.
Also 1.5. That's how the index of refraction is defined.
Where is the only location where a converging mirror will not produce an image?
When the object lies within its focal length then no real image can be produced
If you meant optical density by the term 'denser ' Then the answer is....
The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
How do you find the speed of light in jello using the angle of incidence and angle of refraction?
Use Snell's Law.
Snell's Law is:
Sin i divided by Sin r, where "i" is the angle of incidence and 'r" is the angle of refraction.
It's 1/0.8 = 1.25
What was the earliest model of LASER and what was it called?
Because the initial work on "Amplification by Stimulated Emission of Radiation" (ASER) had been done on microwaves and such a device was thus named the MASER, the earliest work on what is now called the LASER referred to them as the "optical MASER".
On May 16, 1960, Theodore H. Maiman operated the very first functioning LASER at Hughes Research Laboratories, Malibu, California. Maiman's LASER used a solid-state flashlamp-pumped synthetic ruby crystal to produce red light, at 694 nanometers wavelength; however, the device was only capable of pulsed operation, because of its three-level pumping design scheme. Later that year, Ali Javan, and William R. Bennett, and Donald Herriott, constructed the first gas LASER, using helium and neon that was capable of continuous operation in the infrared (U.S. Patent 3,149,290 Bell Labs).
