How long does it take light from the Sun to reach the Earth if it travels a distance of 1.5 10 11m velocity of light 3/10 8m s?

Unlock Therefore, light travelling at 3.0×10^8 meters per second takes 500 seconds (8 minutes, 20 seconds) to reach the Earth, which is 1.5×10^11 meters away from the sun.

What is the speed of light to reach Earth from sun?

299,792 kilometers per second
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.

How far is the Sun from the Earth in light minutes?

8.317 light-minutes
For example, a light-minute is 60 light-seconds, and the average distance between Earth and the Sun is 8.317 light-minutes.

How do you calculate the speed of light in space?

The Speed of Light in a Vacuum Is a Universal Constant Einstein’s equation, and one of the most famous equation in physics, ​E = mc2​, provides the clue as to why this is so.

How long does it take light to travel 1 meter?

Time, straight lines and light The way we measure distances now depends on this speed: the speed of light has been defined as 299,792,458 metre inverse second since 1983. So a metre is now how far light travels in 1299,792,458 second.

What is speed of light km?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

What is the formula of speed of light?

Formula: c = f where: c = the speed of light = 300,000 km/s or 3.0 x 108 m/s. = the wavelength of light, usually measured in meters or Ångströms (1 Å = 10-10 m) f = the frequency at which light waves pass by, measured in units of per seconds (1/s).

Why is the speed of light finite?

That something, the universal conversion factor, is the speed of light. The reason that it is limited is simply the fact that a finite amount of space is equivalent to a finite amount of time. Mathematically, the wave equation that describes light as an electromagnetic wave would lose its time-dependence.

What is the speed of light in miles per hour?

Answer The speed of light in miles per hour is 6.702 x 10 8 miles/hr.

How long does it take a light to reach the Moon?

Please enter distance or time, the other value will be calculated. One year is counted as 31557600 seconds (365 1/4 days). Examples: the average distance of the moon from earth is 384400 kilometers. The light takes just under 1.3 seconds to get there. For one centimeter, light takes 3.3e-11 seconds.

How long does it take for light to travel one centimeter?

For one centimeter, light takes 3.3e-11 seconds. These are 0.000000000033 seconds (first digit ≠0 at the 11. decimal place).

Why does time shrink over time?

Because relativity. From your frame of reference it indeed does shrink. From the frame of reference of an outside observer, you still take years but your clocks appear to run more slowly, aka time is running more slowly for you than for the outside observer. I still don’t understand.
