Does a substance having high optical density have to have a high physical density?
No, a substance with high optical density does not have to have a high physical density. Optical density refers to how much a material can absorb or reflect light, while physical density refers to the mass of the material per unit volume. These properties are not directly related.
Why high concentration HAVE high optical density?
High concentration of a substance leads to high optical density because more particles are present in the solution, resulting in increased scattering or absorption of light. This increased interaction with light causes a greater reduction in light intensity, making the solution more opaque and resulting in higher optical density.
Most optical telescopes used by professional astronomers are in?
Most optical telescopes used by professional astronomers are located on mountains or remote locations away from city lights to minimize light pollution and atmospheric disturbances. Some observatories, such as those in Chile and Hawaii, are known for having excellent observing conditions due to high altitudes and clear skies. Telescopes are also placed in space, like the Hubble Space Telescope, to avoid atmospheric interference.
What is optical recording equipment used for?
Optical recording equipment is used to digitally store and retrieve data on optical discs such as CDs, DVDs, and Blu-ray discs. These discs use a laser to read and write data on a reflective surface, allowing for high-capacity storage of music, videos, software, and other digital content.
Why is it possible for a high mountain to be covered by snow?
The high altitudes cause it to be colder.
Is it true that a DVD-ROM is a high capacity optical disc?
Yes. Although there are more high capacity disks out there.
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
DVD-ROM is a high capacity?
optical dish
Does a substance having high optical density have to have a high physical density?
No, a substance with high optical density does not have to have a high physical density. Optical density refers to how much a material can absorb or reflect light, while physical density refers to the mass of the material per unit volume. These properties are not directly related.
What is electronic bottleneck?
Electronic bottleneck refers to the inability of electronic devices to process optical data at very high speeds. The term is used mostly when trying to justify the need to process ultra high speed data using all-optical devices without the need for optical-electrical-optical conversion.
Why high concentration HAVE high optical density?
High concentration of a substance leads to high optical density because more particles are present in the solution, resulting in increased scattering or absorption of light. This increased interaction with light causes a greater reduction in light intensity, making the solution more opaque and resulting in higher optical density.
What optical fibers made of?
High purity glass strands.
What are the advantages and disadvantages of optical computers?
advantages:- high speed ,high parallelism,less consumption,less heat released,less noise,less wear and many more disadvantages:- optical components are expensive,optical components are not miniaturized ,problem of exact manufacturing ,incompatibilty
A high-powered laser light creates the on an optical disc?
pits
What are optical fibers made of?
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.
Why are big telescopes found on top of mountains?
The Earth's atmosphere provides interference to optical telescopes because the molecules in the air scatter and disrupt light. Many telescopes are placed at high elevation because the atmosphere is thinner and will cause less interference.
High capacity optical disk?
DVD RoM
