Question #8aaf2

Answer 1

I make it about 2.86 meters

Explanation:

105 MHz means that 105 Million wave crests pass a given point every second. These waves are travelling at the speed of light, 300,000 km/sec.

So, 105 Million wave crests = 300,000 km.

Divide both sides by 105 million:

`(105 * 10^6)/(105 * 10^6) = (3 * 10^5 km)/(105 * 10^6)`

`= 2.86 * 10^(-3)km`

...or 2.86 meters (rounding)

GOOD LUCK
