It travels at the speed of light! Which computes to 1 second to travel approximately 300,000,000 metres (186,282 miles) when travelling through space. It takes about 8.32 minutes for the Sun's light to reach the earth.
In space (a total vacuum) it actually travels at precisely 299,792,458 metres (about 186,282.397 miles) per second. Air slows it down a bit, water slows it down a bit more, and when light passes through a diamond it goes at about 41% of that speed, i.e. a measly 76,375.8 miles per second.

What else can I help you with?
What are the speeds of a long wave light compared to a short wave light?
Long wave light travels at a slower speed than short wave light in a vacuum. This is due to long wave light having a lower frequency and longer wavelength, causing it to interact less with the surrounding medium compared to short wave light.
What are wave lengths in your eye?
The visible light spectrum enters the eye and is focused onto the retina at the back of the eye. The eye's photoreceptor cells, known as rods and cones, are sensitive to different wavelengths of light. Cones are responsible for color vision and are sensitive to different wavelengths corresponding to the colors red, green, and blue.
How do you calculate wave lengths?
To calculate the wavelength of a wave, you can use the formula: wavelength = speed of the wave / frequency of the wave. The speed of the wave is usually the speed of light in a vacuum (3.00 x 10^8 m/s). The frequency of the wave can be found by counting the number of wave crests passing a point in one second.
What is a range of wave lengths called?
A range of wavelengths is called a spectrum. This can refer to electromagnetic waves like light, or other waves such as sound or seismic waves.
What type of wave is a light wave an example of?
Light is an example of a electromagnetic wave.
What has wave lengths longer than the wave lengths of visible light?
Radio waves, microwaves and infrared light have a longer wavelength and lower frequency than visible light.
Do light waves or gamma rays have shorter wave lengths?
I assume by light rays, you mean visible light rays. In this case, gamma rays have shorter wave lengths.
Is speed of light is the same for all the wave lengths?
yes
What do you call light divided into wave lengths?
You probably mean "Spectrum".
Different wave lengths of visible light result in different?
...colors when the light enters your eyes.
What is the form of energy with wave lengths that are shorter than violet light?
Ultraviolet.
What are the speeds of a long wave light compared to a short wave light?
Long wave light travels at a slower speed than short wave light in a vacuum. This is due to long wave light having a lower frequency and longer wavelength, causing it to interact less with the surrounding medium compared to short wave light.
Do all colors have the same wave lengths?
The visible light part of the electromagnetic spectrum is below the ultraviolet but above infrared. Purple light has the highest wave length and red has the lowest.
Longest color wave lengths?
There is no longest wave-length for light. It can be infinitely long (just as light waves could be infinitely short). The longest visible light that humans can see is about 750 nanometers long, which is 0.00075 of a millimeter. This color would be a shade of red. Some other animals and insects can see slightly longer wavelengths, and many can not even see what we can.
What kind of light does a csi use to find blood?
it's called an ALS alternate light source. it can project light in different wave lengths and spectrums.
What radio waves are made of?
Radio waves are electromagnetic energy, similar to light, but of much longer wave lengths.
Is radation from a microwave dangerous for a pregnant woman?
No. It is totally safe for pregnant women. As such all radiations with wave lengths longer than light wave are safe for pregnant women.
