How long does it take light to travel from the Moon to Earth?
How long does it take light to travel from the Moon to Earth?
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. In other words, the Moon is 1.3 light-seconds away from the Earth.
How far does light travel in 1.3 seconds?
Light travels the 380,000 kilometers (240,000 miles) between the Moon and the Earth in 1.3 seconds. It would take a person more than nine years of continuous walking to travel this distance.
What is the distance between Earth and moon answer?
When the moon is at its farthest distance from Earth, known as apogee, it is about 251,000 miles (405,500 km) from our planet.
How far is the Earth away from the Moon if it takes 1.3 seconds for the waves to travel from Earth to the Moon?
It’s also about 380,000km away, so it takes 1.3 seconds for light to travel from the moon to us. We see the moon not as it is, but as it was 1.3 seconds ago.
What is the speed of light in KM?
Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).
How far away is the Moon in light minutes?
In astronomic terms, the Moon is 1 AU (astronomical unit) away from the Sun. In light-years, the Moon is 8.20 light minutes away, or 500 light-seconds away from the Sun. At the farthest point in its orbit, the Moon is around 152 million km / 94.5 million mi, a little over 1 AU away from the Sun.
What is the speed of light 3×10 8?
The speed of light in vacuum is 3×108 m/s. Sunlight takes about 8 minutes to reach the Earth.
How do you calculate light distance?
- A light year is a distance.
- It is the distance light travels in one year.
- As light travels at constant speed, the distance light travels in a year can be calculated using the equation:
- Distance = speed x time.
- time = 1 year = 365 x 24 x 60 x 60 = 31,536,000 s.
- A light year is a distance.
- It is the distance light travels in one year.
- As light travels at constant speed, the distance light travels in a year can be calculated using the equation:

What distance will light travel in 1 second?
The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second — a universal constant known in equations as “c,” or light speed.
What is the distance between Earth and moon Class 9?
The answer is option B , the exact distance between earth to the moon is 384,400 km. By the option, 4,00,000 km is the approximate answer to this question.
How do you calculate the distance from the Earth to the Moon in Class 9?
Assume earth and moon as point masses and no other force by any other body. Earth=6*10^24kg. Moon=7.2*10^22kg. Distance=384000.
What is the distance between the Sun and the Earth Class 8?
The distance is about 147 million km (91.3 million miles).
Why the Moon takes 27.3 days to orbit the Earth and yet there are 29.5 days from one full moon to the next?
It takes the Moon 27.3 days to make a complete orbit around the Earth, but because the Earth is moving around the sun at the same time, it takes the moon 29.5 days to go through its eight different ‘phases’ – a lunar month.
Why is it 13 minutes on the Moon?
Thirteen minutes is the time it took the gold-wrapped, four-legged Lunar Module to reach the moon surface after separation from the command module, which remained in orbit around the moon. The BBC podcast 13 minutes to the Moon tells the story of how incredible the moon landing was in fact.
How many minutes are required for sunlight to reach the Earth if the Sun is 1.50 x10 8 km from the Earth?
It will take about 8 min and 20 s for the sunlight to reach Earth.

How many light years is the Moon from the Earth?
How old is the light we see from the Sun?
The sunlight we see is 170 000 years and 8.5 minutes old. It is ancient!
How long does it take for light to travel 1.5 million km?
We orbit the Sun at a distance of about 150 million km. Light moves at 300,000 kilometers/second. Divide these and you get 500 seconds, or 8 minutes and 20 seconds. This is an average number.
