Can someone explain the difference between the energy from a microwave
oven, that coming from an analogue cordless phone and wi-fi? I'm a bit confused (probably in part because I am so zapped in this frikking house). Thanks! Aline |
Hi Aline,
Perhaps I have a simple way of looking at the differences you seek: There are 3 sets of numbers for each of your 3 examples. 1. Frequency, measured in MegaHertz 2. Amplitude, or energy output in Watts 3. and the wave form shape. Analogue sine wave or Digital square wave Imagine the lower frequency of an old cordless phone (860-960Mhz) as the lower frequency in a rainbow (Red). a GSM900 is between 890-960 Mhz is also Red, a DECT1 at 1890 Mhz or GSM18K phone around 1800 MHz could be Orange a microwave oven at 2450Mhz could be Yellow the newest wireless internet around 3600 Mhz could be Green a DECT2 or WIFI around 5250 Mhz could be Blue. Amplitude is brightness. and imagine the Digital as pulsing like a jackhammer. So the difference between the energy coming from: a microwave oven (Bright Yellow) and an analogue cordless phone (wavering less-bright Red), and Wi-fi (pulsing and flashing blue). How's that for a visual? And to get some sleep or restorative rest, you need a Dark or Black room.

Thanks Stewart, that is very helpful.
I will print out your colorful description and try and get a grasp of it. Aloha, Aline --- In [hidden email], "S.

Nice illustration Stewart!
The digital pulsing "jackhammer" wave can also be contrasted with a sine wave which is like ripples on a pond or the waves of a smooth ocean swell (not breakers or surfers' crests though!)
