The speed of light is about 300,000 kilometers per second in a vacuum. In air, it is bout 90 kilometers per second slower. Light speed is a constant regardless of the frame of reference of the observer, but it's speed has been proven to be affected by different mediums.
ans2. Light is an electromagnetic phenomena, and is unaffected by the motion of air.
No. Light in vacuum is roughly 880 thousand timesas fast as sound in air.
Light can travel in the form of electromagnetic waves or photons. In a vacuum, light travels at a speed of 299,792 kilometers per second. When light encounters a medium like air, water, or glass, it may be absorbed, reflected, or refracted depending on the properties of the material.
The speed of light in air is approximately 350 meters/second. It is not constant; it depends on pressure, temperature, and humidity.
Light will not travel into silver.
Not normally.Not normally.
it is 3.5 billion times fast in a milli-second I don't know where this answer came from or what it means BUT - sound travels at roughly 700 mph in air at sea level; - light travels at 186,000 miles per second in a vacuum; - assuming we compare sound in air (as it can't travel in a vacuum) and light in a vacuum (as it can slow through a medium such as air or water), then light travels at 830,000 times the speed of sound.
It is fast, Jacob....
Yes, light waves can travel through air because air is a medium through which electromagnetic waves can propagate. Light travels at different speeds through different mediums, but it can definitely travel through air.
yes. if light didn't travel through air, then you wouldn't be able to see anything!
Since air has a lower optical density than water, light waves can travel faster in air.
Sound waves require a medium to travel through, such as air, water, or solids, and they propagate by causing particles in the medium to vibrate. Light waves, on the other hand, can travel through a vacuum and do not require a medium. They propagate as electromagnetic waves and can travel through empty space.
