What else can I help you with?
How much in a centimeter?
It is the distance that light travels in 1/299 792 458 00 of a second in vacuum
Why Refractive index the medium is always greater than 1?
The refractive index indicates how much light is slowed down as it travels through a medium compared to its speed in a vacuum. Since light travels more slowly in a medium than in a vacuum, the refractive index of the medium is always greater than 1.
How much is one milimeter?
1 millimetre is the distance light travels in 1/299 792 458 000 of a second in vacuum
What is the difference between the speed of light and the speed of sound?
The speed of light is much faster than the speed of sound. Light travels at approximately 186,282 miles per second in a vacuum, while sound travels at about 1,125 feet per second in air.
What is the difference between light and sound?
Light and sound are both forms of energy, but they travel in different ways. Light travels in straight lines as electromagnetic waves, while sound travels as mechanical waves through a medium like air or water. Light can travel through a vacuum, but sound needs a medium to propagate. Additionally, light travels much faster than sound, with a speed of about 186,282 miles per second in a vacuum, while sound travels at a speed of about 1,125 feet per second in air.
What does the light travel faster than the sound?
Light travels faster than sound because it does not require a medium to travel through, whereas sound does. Light travels through the vacuum of space at a speed of approximately 186,000 miles per second, while sound travels through air at a much slower speed of about 1,125 feet per second.
What travels the slowest sound or Light?
Sound travels much more slowly than light. This is why we see the flash of lightning before we hear the thunder.
Is a echo faster than light?
No, an echo is not faster than light. Light travels at the fastest speed possible in the universe, which is approximately 299,792 kilometers per second in a vacuum. Sound, including echoes, travels much slower than light, at about 343 meters per second in air.
Suppose light travels 15 times faster in a vacuum than it does in glass What is the index of refraction for glass Express your answer as a decimal?
The index of refraction for glass is 1.5. This value is calculated by dividing the speed of light in a vacuum by the speed of light in the material, which gives us 3.0 (speed in a vacuum) divided by 2.0 (speed in glass). This means light travels at 2/3 the speed in glass compared to a vacuum, resulting in an index of refraction of 1.5.
What is fastest the speed of light or the beat of a fly's wing?
The speed of light ! Nothing travels faster !
Is the speed of light or sound faster?
The speed of light is about 880 thousand timesfaster than the speed of sound.
Which travel faster light or sounds?
Light travels considerably faster.Sound travels at about 343 meters per second. Light travels at 299,792,458 meters per second.Light in vacuum travels about 876 thousand timesas fast as sound in air.If you meant to ask if light or sound travels faster then this is the answer:Light travels faster, with a speed of 300,000,000 m/s (which is equal to 300,000 km/s, or 186,282 miles per second). Sound, on the other hand, travels at a speed of 340 m/s (which is equal to 1126 ft/s).
