What two things must an astronomer find out in order to calculate a starts absolute brightness?
Three things, really. An astronomer needs to determine the apparent brightness of a star or other object, and needs to know its distance. He would also need to have an estimate about extinction - that is, how much of the light is absorbed on its way.
When an astronomer says she is going to study light how many different types of light can she study?
All the types on the electromagnetic spectrum (e.g. infrared, ultraviolet, visible, radio, etc.)
Was Galileo the first scientist to estimate the speed of light?
Yes I THINK.But he was only measuring from one mile so he got 0.000005 sec.
What type of scientists is most likely to study meteor flying through outer space?
Astronomer
Who said the moon does not shine by its own light?
Every scientist, astronomer, astrologer and person with more than a third grade education.
Who was the danish astronomer who made the first rough estimate the speed of light in 1676?
It was Ole Rømer: http://en.wikipedia.org/wiki/Ole_R%C3%B8mer
What was the Danish astronomer who made the first estimates the speed of light in 1676?
Ole Roemer was.
What is the contribution of Olaf Roemer in physics?
he is the Danish Astronomer who made the first rough estimate of the speed of light in 1676 by measuring the length of time and eclipse that occured in one jupiter's moons.
Who was the first to measure the precise speed of light?
The Danish astronomer Olaus Roemer was the first to measure the speed of light. (within 25 % of the actual value)
Who were the persons were mesured speed of light?
It was the Danish astronomer, Olaus Roemer, who, in 1676, first successfully measured the speed of light. His method was based on observations of the eclipses of the moons of Jupiter (by Jupiter).
What is the contribution of Ole Roemer to physics?
The Danish astronomer Ole Christensen Rømer made the first quantitative measurement of the speed of light in the year 1676. A link can be found below for more information.
Who first estimated the velocity of light?
Prof. K. Smiles Mascarenhas, Coimbatore, India says: " An astronomer named Chritiansen Roemer gave an estimate of 215,000 Km/sec (the accepted value is approximately 300,000 Km/sec) for the velocity of light in the year 1676. He made this estimate while observing an eclipse of Io, the satellite of Jupiter by the giant planet. He was wrong about the estimate because the radius of the earth's orbit was not accurately known at that time. Still, he can be credited as the first person to estimate such an enormous velocity. The first terrestrial estimate was made by a physicist named Fizzeu through his 'toothed wheel experiment '. Later, the measurements were refined by Michelson"
How did Albert Einstein determine the speed of light?
Albert Einstein did not determine the speed of light, rather that the speed of light was the maximum speed possible in the universe. The speed of light was discovered in the late 1600's by Danish astronomer Ole Roemer, using Jupiter and its moon Io. It was later used in Maxwell's equations of electromagnetism, and then later used by Albert Einstein in his theory of special relativity.
