How do the speed of light and the speed of sound compare through air?
The speed of light is significantly faster than the speed of sound in air. The speed of light in a vacuum is approximately 299,792 kilometers per second while the speed of sound in air is about 343 meters per second. This means that light travels almost a million times faster than sound through air.
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?
About 0.00005seconds in air. The spee of light in air is nearly 300000km/s. So, time required will be 15/300000 seconds which is 0.00005.
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
What happens to the speed of light when it travels from air into glass?
The speed of light decreases when it travels from air into glass because the glass has a higher refractive index than air. This causes the light to slow down as it moves through the denser medium.

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 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
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.
Does Light moves slower through water than through air?
Yes, light moves slower through water than through air because water has a higher refractive index than air. This causes light to bend more when it enters water, resulting in a slower speed.
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 materials can light travel through faster than it travels through air?
Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.
How much time you need for 15km with the speed of light?
About 0.00005seconds in air. The spee of light in air is nearly 300000km/s. So, time required will be 15/300000 seconds which is 0.00005.
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.
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
Does red visible light travel faster through water or through air?
Any electromagnetic wave that can propagate through water at all will do so at a lower speed than when it's in air.
