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:
What colors do you mix to get a light cherry?
Mix red and white to achieve a light cherry color. Adjust the ratio of red to white to get the desired shade of light cherry.
What two colors can be mixed to get light green color?
To get a light green color, you can mix yellow and blue together. Adjust the ratio of each color to achieve the desired shade of light green.
What color tube that requires a 1.9 ratio of anticoagulant to blood?
A light blue tube typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.
Is a photometer an instrument that measures the intensity of the incoming light and quantifies it into numerical data?
Yes. A photometer is an instrument that measures the intensity of the incoming light and quantifies it into numerical data. A photometer is a light sensitive device and measure the power of light.
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.
What do light years measure in astronomy?
Light years measure distance in astronomy. It is the distance that light travels in one year, which is about 9.46 trillion kilometers.
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.
How do you measure light years and what does it signify in astronomy?
Light years are a unit of measurement used in astronomy to indicate the distance that light travels in one year. This distance is about 5.88 trillion miles. Light years are significant in astronomy because they allow scientists to measure vast distances in space, such as the distance between stars, galaxies, and other celestial objects.
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 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 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 astronomy words start with the letter z?
Zenith, zodiac, zodiacal light.
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 is the ratio of velocities of light of wavelength 8000angstrom and 4000angstrom?
The ratio of their speeds is 1.00000 . In vacuum, all wavelengths of light, and of all other forms of electromagnetic radiation, have the same identical speed.
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.
Why is astronomy necessary?
Astronomy can confirm things that you can't see on earth due to gravity and the atmosphere - things like the absolute speed of light (light in a vacuum) or what is the sun made of? Informaiton about other places often tells us about our own home.
