Probably the type of bulb you are using. Traditional incandescent bulbs don't turn on that way. There are many bulb types that work that way, and it is completely normal and safe in that situation. When in doubt though, call an electrician. If there is a problem, it could cause a fire. I doubt that there's really an issue there though unless it just started happening without anything changing that you know of.
From the Sun, it takes about 500 seconds. That's 8 minutes and 20 seconds.
Moonlight takes 1 min 3 seconds to reach earth.
It takes about 1.3 seconds since the distance between the Earth and the Moon is 230,100 miles and light travels 186,282 miles per second.
138 seconds ± ~53 seconds. Since the orbit of Venus is on a different path than the orbit of the Earth, the time that it takes for the light to become visible on Earth from Venus actually varies, but not by too much. 2 minutes and 18 seconds is only at one point in the year, but the distance from Earth to Venus varies so one can also conclude that the time it takes light to reach Earth from Venus varies directly with the time as well. So, the time it takes for the sun is 138 seconds ± ~53 seconds depending on where the planets are in their orbit.
It takes about 8 minutes 20 seconds for light from the Sun to reach the Earth.
about 480 seconds
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
The ray of light hitting a mirror is called an incident ray. It represents the path that light takes before it reflects off the mirror's surface.
From the Sun, it takes about 500 seconds. That's 8 minutes and 20 seconds.
8 minutes and 31 seconds
The Sun is 92,700,000 miles from Earth, and it takes light 499 seconds to come that far, so another answer is "499 light-seconds."
"What is Light, Alex?"Light takes 8 minutes 20 seconds to travel from the Sun to the Earth.
It takes about 997.186 seconds for light to travel across the diameter of Earth's orbit.
i think it takes about 10 seconds if you already have the light bulb in your hand.
It takes about 8 minutes 20 seconds for light to travel from the Sun to the Earth.
Moonlight takes 1 min 3 seconds to reach earth.
At the speed of light it takes 4 hours 11 minutes and 27 seconds.
