How many hours is 3615 km?
That's a distance, and there's no direct conversion between distances and time. If you'd given a speed, then it'd be possible to calculate a travel time.
How do you calculate speed of a distance time graph?
Speed (in the radial direction) = slope of the graph.
What is the speed of light in kilometers per hour?
The speed of light is 1,079,252,848.8 kilometers per hour.
How do you calculate speed using distance and time?
Distance divided by speed will give you the time it took to travel the distance.
How do you calculate the frequency of a wave?
Divided the wave's speed by its wavelength.
What is the unit that astronomers most often use to express the wavelength of light?
Speed of light
What are some of the ways astronomers have measured interstellar distance?
speed of light
Why is the galaxy measured in light years rather than kilometers or miles?
Galaxies are measured in light years because they are incredibly vast, and light years are more useful for expressing these immense distances. A light year is the distance light travels in one year, which is a more convenient unit than kilometers or miles when dealing with astronomical scales.
Why don't astronomers measure distances in space by the speed of sound rather than the speed of light?
Astronomers use the speed of light for measuring distances in space because light moves much faster than sound. Since the distances in space are vast, using the speed of sound would result in impractically long times for the signals to travel, making measurements less accurate and efficient. Additionally, light travels through the vacuum of space, where sound cannot propagate.
Which formula you use to calculate for the speed of light in water?
Speed of light in water = speed of light in vacuum/refractive index of water
Light velocity is186000 using the light velocity when did supernova actually occurred relative to when the Chinese astronomers saw the explosion?
SN185, the first supernova recorded by Chinese astronomers in 185 AD, is estimated to be 8200 lightyears away from us. As such, the actual time of the explosion is estimated to be 8015 BC.Since large astrometric distances are measured in light years, it is not necessary to know the speed of light or use it in any calculation, for the purposes of answering this question.
Do all planets revolve around the sun at the same speed?
No. Each moves at a different speed. We can calculate that speed of orbit by knowing the distance of the orbit and the mass of the Sun. When observing other bodies, such as the moons of Jupiter and Saturn, we can use the observed distances and orbital times to calculate the mass of Jupiter or Saturn! Astronomers observing nearby stars are able to detect the faint decrease in light as a planet "transits" the star, passing between the star and us on Earth. Because they are able to precisely measure the time for each orbit, they are able to calculate the mass of the primary star much more accurately!
What is the different astronomers that had a hand in creating the theory and then proving the speed of light?
Leonardo da Vinci
How do you calculate the frequency of light waves?
by dividing the speed of light with its wavelength
Why do astronomers use light-years to measure distance in space?
Astronomers use light-years (ly) to measure distances in space because space is simply so large. Light travels very fast, so it can easily be used to measure distances without resorting to large scientific notation numbers. Inside the solar system, they use the astronomical unit or AU. It is The distance from the Earth to the sun or 93 million miles. Simply put: D. The distances are too great to measure in Earth units. For example, 1 AU = 149,598,000 kilometers = 92,955,887.6 miles 1 ly = 9.4605284 × 1012 kilometers = 5.87849981 × 1012 miles
How do astronomers determine the speed at which a galaxy is moving?
Astronomers determine the speed at which a galaxy is moving by measuring the redshift of light coming from the galaxy. The redshift is caused by the Doppler effect, which shifts the wavelength of light depending on the motion of the source. By analyzing the redshift, astronomers can calculate the velocity of the galaxy relative to Earth.
How do people calculate the speed of light?
by asking robel
