FREE ESSAY ON FREQUENCY

FREQUENCY

Frequency is the number of complete oscillations a wavelength makes each second. Frequency
is measured in hertz (Hz) and when there are one million hertz there are called megahertz
(MHz). A complete oscillation is when the wavelength reaches the same spot from where it
started. To find frequency you use the equation f=1/T where T equals time. T is the time
it takes for a wavelength to complete one oscillation. The equation will give how many
complete oscillations made in one second, which is frequency. 
For a source of frequency I used a 900 MHz cordless telephone. To find frequency I used
an oscilloscope, which measures the time for complete oscillations, which is equal to T
so I could plug T into the equation. The oscilloscope is hooked up to the antenna of the
cordless phone, which is what puts out the frequency.
To cool the antenna of the phone I used ice to cool it down and a thermal blanket to heat
it up. After I reached the temperature of the antenna I hooked the oscilloscope to the
antenna and then I measured the frequency.
