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
