Trough vacuum, it'd be 2.997.924.562 metres/second;
Through air, it'd be 2.997.025.450 metres/second;
both round to 3.000.000.000 metres/second, or 300.000 kilometres/second.

How do the speed of light and the speed of sound compare through air?
The speed of light through air at sea level is roughly881 thousand times the speed of sound.
What is the speed of visible light waves when traveling through air at normal temperatures and pressures?
The speed of light in vacuum is exactly 299.792,458 m / s The speed of light in air is roughly 299,702,458 m / s
How much time you need for 15km with the speed of light?
Since the speed of light is approximately 299,792 kilometers per second, it would take only around 0.00005 seconds to travel a distance of 15 kilometers at that speed.
Which is faster the speed of sound in air or the speed of light in air?
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Where is the speed of light greater than the speed of light in water?
The speed of light through vacuum is constant. The speed of light through air is slightly less. The speed of light through water or some other medium is even less than that. The factor by which the speed of light (and its wavelength) is reduced within a medium is called the "index of refraction" (which determines the amount of bending that occurs when light goes from one medium to another).
How do the speed of light and the speed of sound compare through air?
The speed of light through air at sea level is roughly881 thousand times the speed of sound.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
Does Light moves slower through water than through air?
The speed of light is constant
Can the speed of light depend on air temperature?
The speed at which light travels through a substance such as air depends on its density, which in turn depends in part on temperature.
Is this true or false that light moves slower through water than through air?
Yes it is true. If c is the speed of light in air then in water it will be 3/4 of c Hence refractive index of water = speed of light in air/speed of light in water So refractive index = 4/3 = 1.333
What is the speed of visible light waves when traveling through air at normal temperatures and pressures?
The speed of light in vacuum is exactly 299.792,458 m / s The speed of light in air is roughly 299,702,458 m / s
What is the speed of light on earth through air?
299,792,458 meters/second
Why does the speed of light vary?
The speed of light varies because the absolute speed of light "C" is measured in a vacuum. When light travels through air, it goes slightly slower. When light travels through denser mediums still, such as glass, the speed decreases further still.
How much time you need for 15km with the speed of light?
Since the speed of light is approximately 299,792 kilometers per second, it would take only around 0.00005 seconds to travel a distance of 15 kilometers at that speed.
Which is faster the speed of sound in air or the speed of light in air?
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Through which does light travel best?
Speed of light is fastest through vacuum. Although it is only about 0.001 times slower in air.
What happens when a light ray travels through air into glass?
Light speed slows down in the glass.
