How far can light travel in one year quizlet?
A unit that equals the distance light travels through space in one year; a way to measure extremely vast distances; it equals 9.46 trillion kilometers or 9.49 x 1012 km.
Why does it take the light 8 minutes to reach us from the Sun?
Light travels at a speed of 300,000 kms−1 and the distance between Earth and the sun is 150 million km. Thus it takes nearly 8 minutes for light from the sun to reach Earth.
Why does it take 8 minutes for light from the Sun to reach the Earth?
The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago.
Does 1 light year equal 1 year?
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

Is 1 light-year the largest distance?
The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km). At first glance, this may seem like an extreme distance, but the enormous scale of the universe dwarfs this length. One estimate puts the diameter of the known universe at 28 billion light-years in diameter.
How long does light from the Moon take to reach Earth?
How far is that in light-seconds? Light travels at 300,000 kilometres per second, so it takes about 1.3 seconds for light to travel from the Moon back to the Earth.
How long does it take light to reach Earth from Moon?
Light travels through space at just over 186,000 miles per second. The moon is just under 250,000 miles from Earth, so light from the Moon’s surface has to travel more than one second (about 1.3 seconds) to reach earth.
Why do we see the Sun 2 minutes after the sunset?
It is because of atmospheric refraction. When the Sun is slightly below the horizon, the light coming from it travels from less dense to more dense air and is refracted downwards. Thus, the Sun appears to be raised and can be seen 2 min before actual sunrise and 2 min after actual sunset.
How long does it take light to travel from the Sun to Earth in seconds?
