How long will it take the light from a flashlight to travel around the Earth once?
Well it won't as light can't turn only go straight from its source.
It almost could if you used fiber optics, and then if you used fiber optic cable the loss in the cable would have the light completely gone long before the light made it around the world.
But the math Speed of light = 299,792,458 METERS PER SECOND
Circumference of the Earth = 40075.16 km
Math MPS to KMPS 299792458 / 1000 = 299,792.458 Kilometers per second
40075.16 km / 299792.458 kmps = .1336 seconds

Is a flashlight good model for suns light energy hit earth?
Flashlight is not good model to test sun light hit earth. The light of flashlight is too small energy to compare sun light.
How long would it take light to traver around the world?
Light travels at approximately 186,282 miles per second. The circumference of the Earth is about 24,901 miles. Therefore, it would take light approximately 0.133 seconds to travel all the way around the Earth.

How far does the light from a flashlight travel?
The distance light from a flashlight travels depends on the brightness of the light, atmospheric conditions, and any obstacles in its path. Typically, light from a flashlight can travel several hundred feet in the dark before becoming too dim to be visible.
How do you know the speed of light is correct since a light wave has no beginning or end it would seem impossible to measure?
Turn your flashlight on and off. The light wave begins and ends. The light wave from your flashlight will take 1 nanosecond to travel one foot from your flashlight.
When you turn on a flashlight does it experience any force associated with the emission of light?
No, when you turn on a flashlight, the emission of light does not exert a force on the flashlight itself. The light is simply released in the form of photons, which travel in straight lines until they interact with something else.
How long would it take light to traver around the world?
Light travels at approximately 186,282 miles per second. The circumference of the Earth is about 24,901 miles. Therefore, it would take light approximately 0.133 seconds to travel all the way around the Earth.
How light travels from a flashlight?
In a straight line. At the speed of light.
For the moon to travel at the speed of light how long would it take to orbit the earth?
It takes about 1.28 seconds for light to travel from the moon to Earth. So if the moon were to travel at the speed of light, it would complete an orbit around the Earth in approximately 1.28 seconds.
In one minute how many times can light travel around the earth?
7
What is the speed of a flashlight when it turn's on?
The speed of light from a flashlight is the speed of light, which is approximately 299,792 kilometers per second in a vacuum. When you turn on a flashlight, the light it emits will travel at this constant speed until it interacts with another medium.
Why is the beam of light from a flashlight that shining in fog straight?
scattered light
