Question 587993
The wavelength, w, of a radio signal is inversely proportional to its frequency, f. When f = 200, 
w = 1500. 
(a) Find an equation connecting f and w. 
f*w = k = 200*1500 = 300000
Freq in KiloHz*wavelength in meters = c, the speed of light in km/sec
---------------
(b) Find the value of f when w = 600.
f = 300000/600
f = 500 KHz
