When you look at a pencil in a cup of water and see a distorted image of the pencil it is called "Refraction". I have seen many people post statements saying light is not affected by temperature. This is incorrect. A mirage on the highway is a perfect example. Mirages are caused by hot air near the ground refracting, or bending, light rays upwart into the eyes of a distant observer.
Speed of light in a vacuum = 3.00 x 10^8 m/s
Refraction of Air at 30oC = 1.00026
Formula: n = c/v
v = 3.00 x 10^8 / 1.00026
v = 2.99 x 10^8
What else can I help you with?
What is the speed of light when traveling through air at 0 degrees Celsius?
The speed of light in air at 0 degrees Celsius is about 299,702,547 meters per second. This speed can vary slightly depending on factors such as air density and composition.
What is the speed of light at 30 degrees?
That would depend on the medium which the light is traveling through.
What is the critical angle for light traveling from water into air?
48.6 degrees
When is the speed of light the fastest?
When the light is traveling through vacuum.
Is sun freezing?
No, the sun is not freezing. The sun is a massive star that generates heat and light through nuclear fusion in its core. Its surface temperature is around 5,500 degrees Celsius (10,000 degrees Fahrenheit).
What does the speed of light and the speed of sound travel through?
The speed of air at 20 degrees Celsius is 343 meters per second. The speed of light is 299 792 458 meters per second.
Can light travel without air?
Yes. In fact light traveling through air moves slower than when traveling through a vacuum. Light traveling from the Sun travels through space which is almost a vacuum. Stars are suns and light from them goes through the interstitial areas between galactic clusters which is very close to a total vacuum.
Is it hazzardous to turn a light on and off by just loosening it from the socket?
Switching light on/off through loosening from socket is not advisable. Light bulb can reach at temperature between 200-260 degrees Celsius and it can be hazardous in physical contact.
What is hotter a light bulb or lava?
Lava is significantly hotter than a light bulb. While a typical incandescent light bulb operates at temperatures around 200 to 300 degrees Celsius (392 to 572 degrees Fahrenheit), lava can reach temperatures between 700 and 1,200 degrees Celsius (1,292 to 2,192 degrees Fahrenheit). Therefore, lava is much hotter than a light bulb.
If the temperature is 39 degrees Celsius you are most likely to want to wear?
If the temperature is 39 degrees Celsius you are most likely to want to wear?Something light and cool (or even a bathing suit) -- this is the same as 102.2 degrees Fvery little.
Compare the speed of light with the speed of sound at 0 degrees celsius?
The speed of light has nothing to do with the temperature of the vacuum. It is c = 299 792 458 meters per second. The speed of sound has much to do with the temperature of the air. At 0 degrees Celsius the speed of sound in dry air is c = 331.29 meters per second.
How cold can fire be and still maintain its ability to produce heat and light?
Fire can be as cold as 932 degrees Fahrenheit (500 degrees Celsius) and still produce heat and light.
