ha, on my way to work this morning, was suddenly struck by this revelation. Recalled that during my orientation 2 weeks ago, my boss was talking about what are the properties of radio waves.* He mentioned that technically light and sound waves are really the same, just that they moved across space in different frequencies. He used an interesting example that still stuck in my mind. Let say we have a analogue radio, with an infinite spectrum band with which you can change your radio receiving frequency. If you keep on increasing the frequency i.e. tune your band ever "upwards" on the radio, very soon you will be able to see light coming out of the radio. So basically, light and sound waves are all part of the same family.^ You just have to alter the frequency at the source to get different products.
And this morning it suddenly struck me, it's the same with my life. What people hear I say ("radio waves") and what people see I do ("light waves") should basically reflects the same source. To carry it further, if I preach the Word ("radio waves"), but do not do what I preach ("light waves"), or vice versa, there will be very glaring inconsistencies in my life... A sobering thought. Not only must I proclaim the Gospel in my life with my voice, I must affirm the Gospel by having a transformed life.
*Yes, it was like a secondary school lesson on physics. Only difference is that my boss managed to keep the lesson very interesting, even for a non-science/engineering person as me.
On a totally different note, I shudder at the recollection of how my secondary Physics teacher used to teach the lessons - he really killed the subject for me.
^ that will be the family of electromagnetic waves...
Hmm.. I must say that actually there's a huge fallacy in what your boss said. Think he's mixed up sound as part of the EM spectrum, because it's NOT! I.e. you can keep increasing frequency from low freq radio waves all the way to high freq gamma rays and yes you can reach the visible light by doing that. BUT that's LIGHT AND RADIO waves not SOUND waves. Simply put, sound waves are LONGITUDINAL waves, while everything else on the EM are transverse waves. Sound needs a medium for propagation, but light doesn't (that's why the sun's rays can reach earth). Finally, I think you can prob do another post on how an analogue radio converts wave to sound.. =)
ReplyDeletepiangz, thanks for ruining my story.... :P Kidding~
ReplyDeletewell, only an engineer can spots another engineer's mistake. We Arty Farty sorts just lap up all the technical mumbo-jumbo you all throw at us... :D
