Wave Speed = Wave Frequency x Wavelength

You know that the speed of radio waves in a vacuum is 3x10^8 m/s

so you just substitute the values into the equation below.

Wavelength = Wave Speed / Wave Frequency

Wavelength = 3x10^8 / 5x10^9 

Wavelength = 0.06 m

PLEASE HELP -Given the graph of rectangle QUAD and its reflection.
V125BC [204]
Q is located at (-5,2)
Q" is located at  (6,2)
 they bot h have the same Y value (2) so we know it was only a reflection across the X axis
 we need to find out where on the X axis it was reflected.
 the distance between -5 and 6 = 11 units
11/2 = 5.5
the reflection line was 5.5 units to the right of the original Q
 so the reflection line would be X = 0.5
