What is the unit of specific refraction index?
Refractive indices, n, have no units because they are ratios. They are the ratio of the speed light in a vacuum C, (~3x108m/s) to speed of light in the medium vm. Therefore:
Which solid has weakest intermolecular forces?
Well the weakest intermolecular forces is the hydrogen bond because of its friction which is called the fluid friction also if you want to know some astronomy you've come to the right person okay lets start with our basic astronomy the first question is what is the quickest planet in our solar system:ANSWER : Mercury. Well that was basic astronomy ,now where moving on space astronomy which is a bit harder than basic astronomy the second question is which planet has a diameter of 43,000km ANSWER:Jupiter.
What does the term density and refractive index mean?
The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
What is ratio decay?
No such thing as ratio decay. Sorry
What is the ratio of sodium to chlorine to make salt?
The atomic ratio in this salt is 1:1. The mass ratio is 22.999:35.457 of sodium to chlorine, the ratio of the atomic weights of sodium and chlorine.
Why is light an important tool used in astronomy?
Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.
How are light and astronomy related?
Studying light is one part of astronomy. Things like the speed of light, how it travels, the spectrum of light are all things that are used in studying astronomy. Studying light emitted from a star can tell us all sorts of things about it, like how far away it is and how bright it really is.
In astronomy and distances of the universe how much is a ly?
A light year is the distance that light can travel in a year.
What is the name of the amount of sunlight that the surface of the moon reflects?
In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".In astronomy, the amount of light reflected by the Moon - or by any other object - is called "albedo", which literally means "whiteness".
How could light pollution and air pollution effect astronomy?
Light pollution and air pollution effect astronomy by making it more difficult to view the stars. If you notice, when you get out of the cities where there is less air and light pollution, you are better able to view the stars.
What does 'air mass' mean in astronomy?
In astronomy, air mass means the length of light passing through Earth´s atmosphere. Source of light may be from any celestial body. The brightest source of light is the sun and then comes the moon. The moon radiates light reflected from the sun.
What is a measurement of distance based on the speed of light?
A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.
What astronomy words start with the letter z?
Zenith, zodiac, zodiacal light.
How light year is measured?
A light year is a unit of length used in Astronomy to define distance. One light year is equal to just under 6 trillion miles.
The ratio of the speed of light in a medium to the speed of light in a vacuum is called its?
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
What does this field astronomy studies?
- Astrophysics - Observational astronomy - Radio astronomy - Astrometry - Galactic astronomy - Extragalactic astronomy - Stellar astronomy - Solar Astronomy - Theoretical astronomy - Cosmology - Celestial Mechanics
What does ly stand for in Astronomy?
That is short for "light-year" - the distance light travels in a year. Approximately 9.5 million million kilometers.
