WebAnswer (1 of 2): The speed of light is completely determined by two parameters, how well the medium it is traveling through “conducts” electric and magnetic fields. The better the medium conducts electric and magnetic fields, the slower light travels through. Now, consider some material - glass,... Web1 mei 2014 · Today, the speed of light in vacuum, known by the mathematical symbol c, is exactly 299,792,458 meters per second. It is an exact mathematical constant, because the meter was redefined in the International System of Units (SI) in 1983 as the distance traveled by light in a vacuum. So how fast is that, exactly? Really, really fast! In terms …

WebYes, light can travel through a vacuum. In a vacuum, there are no particles for light to interact with. Instead, ... Light is a type of electromagnetic radiation that travels through the vacuum of space. It is the fastest thing in the universe, moving at a speed of 300,000 kilometers per second (186,000 miles per second). WebIn contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. This is why light from distant stars can travel through space for billions of light-years and still reach us on earth. software mart australia review
