How far into space do radio waves travel?

The distance traveled by a radio wave in a vacuum in one second is 299,792,458 meters (983,571,056 feet), which corresponds to the wavelength of a 1 hertz radio transmission and is measured in meters. A 1 megahertz radio wave (mid-AM band) has a wavelength of 299.79 meters and travels at a frequency of 1 megahertz (983.6 ft).

Do radio waves ever stop?

Radio waves don’t cease when they reach a certain distance; instead, they become weaker. Yes, you read it properly. It is due to the fact that the signals are too faint to be comprehended that communications fail at a certain distance.

How fast is a light year in mph?

In a vacuum, light moves at a speed of 670,616,629 miles per hour (1,079,252,849 kilometers per hour). To calculate the distance traveled in a light-year, multiply the speed of light by the number of hours in a year (8,766). One light-year is equivalent to 5,878,625,370,000 miles, according to this calculation: (9.5 trillion km).
