Does a substance having high optical density have to have a high physical density?
It's not necessary. If a compound has high optical density, it means that it absorbs more light at the given wavelength than some reference compound. There is no simple relation between density of matter and optical density. Even more I am pretty sure you can find a lot of compounds with lower densities (of matter) but having high optical density.
Why is it possible for a high mountain to be covered by snow?
The high altitudes cause it to be colder.
If cells are placed in a solution with a high concentration of solute water will?
the molecules will pass from the salt solution to the cells.
How can you get a high score on bubble breaker?
My high score is 1936. I'm curious what the max possible score is?
What instrument is used to measure the temperature of hot metal?
PYROMETER is an instrument for measuring high temperatures esp. in furnaces and kilns
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
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.
What optical fibers made of?
High purity glass strands.
What is optical energy?
Optical Energy, better known as Optical Power, is the converging strength of a lens. As an example a lens with a high Optical Power will have a wider range of view but less focal distance. A lens with low Optical Power will have a longer focal distance but less range of view.
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
