What is a light year and why do scientist use it?
A light year is a measure of how far light can travel in one year. It is a phenomenal distance, and is used to describe how far away stars are from us.
How do you convert 3 earth years into light years?
you cant light years refer to the distance light can travel in 1 year 1 Light Year = 5878625373183.61 Miles
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
Where is analiza balares a filipino scientist year 1990?
There is limited information available about Analiza Balares. It is unclear if she is a Filipino scientist from 1990. It would be best to refer to academic databases or scientific publications for more information.
How does a spectroscope extend a scientist's ability to observe light?
It allows a scientist to measure the wavelength of light.
What is refer by light year?
A light year is the distance which light will travel in a vacuum. Light travels at 299,792,458 m/s in a vacuum, one year is 31557600s (on average taking into account leap years) so 1 light year is 9.46073x10^15m or 9 460 730 473 000 km
What do astronomers use to measure distance to stars?
If you refer to the units, both the light-year and the parsec are often used. A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers (9.5 million million kilometers). A parsec is about 3.26 light-years.
What is use by scientist to measure the distance light travel in one year?
Scientists don't measure the distance light travels in one year. They calculate it by measuring the speed of light. The speed is 300,000,000 meters/sec. and can be measured in the laboratory with a rotating mirror apparatus. To get the distance traveled by light in one year you multiply the speed (above) by the number of seconds in a year. The answer will come out in meters and is also called one light year.
A scientist wants to know whether a particular cell is round or rectangular. How should the scientist observe the overall shape of the cell?
The scientist should use a light microscope.
Is scientist a plural word?
no . . . . . . plural for scientist is scientists.
Why might a scientist use a light meter?
A scientist might use a light meter to measure the intensity of light in a particular environment. This can help them understand how light levels may affect biological processes, growth patterns, or the behavior of organisms.
Which scientist proposed the atom's nucleus contained protons and in what year?
It is the scientist Rutherford. He proposed it in year 1919.
