2-29. Now, let us apply the formula to determine the frequency to which the

receiving equipment must be tuned to receive station WXYZ operating on 240

meters. Radio wave frequencies are normally expressed in kilohertz or

megahertz.

2-30. To find the frequency in hertz, use the formula:

v

f=

λ

Given:

v = 300,000,000 meters per second

λ = 240 meters

Solution:

300,000,000 meters per second

f=

240 meters

f = 1,250,000 Hz

2-31. To find the frequency in kilohertz, use the formula:

300,000

f (kHz) =

λ

Given:

λ = 240 meters

Solution:

300,000

f (kHz) =

240 meters

f = 1,250 kHz

2-32. To find the frequency in megahertz, use the formula:

300

f (MHz) =

λ

Given:

λ = 240 meters

Solution:

300

f (MHz) =

240 meters

f = 1.25 MHz
