The wave length of a radio wave varies inversely as its Freq

The wave length of a radio wave varies inversely as its Frequency. A wave with a Frequency of 1200 kilometers has a length of 300 meters. What is the length of a wave with a frequency of 800 kilometers?

Solution

\"Wavelength varies inversely with frequency\"

W = k/F

K = Constant term \'k\'

300 m = k/(1200 kHz)

k = 360,000 m*kHz

Now putting the value of frequency we got wavelenght

W = k/F

W = 360000/800

w = 450 meter
