Frequency

crest

trough

The number of times something happens per unit time

Modern unit of frequency is the “Hertz”

1 Hertz = 1 Cycle Per Second

Heinrich Hertz

In 1886, first to demonstrate the existence of electromagnetic waves

Frequency

• Hz = Hertz = cycles per second

• KHz = Kilohertz = 1,000 Hz

• MHz = Megahertz = 1,000,000 Hz = 1,000 KHz

• GHz = Gigahertz = 1,000,000,000 Hz = 1,000,000 KHz = 1,000 MHz

(distance between wave troughs)

Frequency is cycles per second:• 1 cycle per second = 1 Hz (Hertz)• if freq = 1,000,000 Hz (1 MHz), then 1 cycle takes 1/1,000,000 sec = period

Speed of Light = 300,000,000 meters per second (speed of radio wave in a vacuum)• if freq = 1 MHz, then in one cycle, radio wave travels

distance = speed x timedistance = 300,000,000 m/sec x (1/1,000,000 sec) = 300 meters = wavelength (λ)

Relationship Between Frequency f and Wavelength Relationship Between Frequency f and Wavelength

Relationship Between Frequency f and Wavelength Relationship Between Frequency f and Wavelength

= c / f

= 300 / f (For in meters, f in MHz)

Bigger f, smaller

Find f, given

We know:

= 300 / f (For in meters, f in MHz)

So,

f = 300 / (For in meters, f in MHz)
