**drwls**, Monday, July 19, 2010 at 8:37pmFor a "radio" or light wave, travelling in a vacuum or air, the speed of the wave is

c = 3.00*10^8 m/s

The wavelength is given by the formula

wavelength = c/f

where f is the frequency.

In your case,

wavelength = 3.00*10^8/1.03*10^6

= 291 m

This can also be written

2.91*10^2 m

I have no clue what the "box 10" refers to. They are trying to say 2.91 times ten-squared. The "box" may be the multiplication symbol, for which I used *.
