About Me

I am a full time specialist Physics tutor operating in Klang Valley. I've been educating student for more than 10 years. My specialty is to transform student that had failed their physics subject into a better result. Even some of them managed to get an A in their final exam, You can read their testimony in this blog. I provide home tuition for physics subject to those living nearby KL especially around W.Maju, Ampang,Melawati and Setiawangsa. At the same time i 'm giving online tuition to all malaysia & overseas student. For tuition centre looking for a physics tutor, i'm also able to give seminar and conduct weekly classes. Meanwhile,for school teachers who are organising physics seminar, i am happy to assist u in that aspect. If u have enquiry on my service, do contact or whatsap me at 017-2877589 or email me at celikfizik @ gmail . com

Getting to know WAVE..

Hi , ive just came back from teaching last nite. I did explain about refraction & diffraction of wave, & the students look a bit blur ..so i gave a 2nd thots & concluded that b4 i go detail about refraction, my student must b able to appreciate these terms; (tak kenal maka tak cinta :)
After reading all these, u guys should check tis out!! Its fun




Amplitude?
As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from its undisturbed position. Just look at figure above!

Wavelength?
It is the distance between a point on one wave and the same point on the next wave. Usually we take the distance between crest(puncak) to another crest.

Frequency, f?
The frequency of a wave is the number of waves produced by a source each second. It comes from a word 'frequent'(berapa kali), it also means how frequent the wave produced per second.
By formula, f= 1 /T and its unit is Hz.
For example,Your PC might be working with a frequency of 4GigaHertz i.e 4000000000000 numbers of data received per second.

Period, T?
It is the time taken for 1 complete vibration or oscillation of a wave. In formula, T= 1/ f

Speed of wave,v?
the speed of wave represented by a formula, v=f λ i.e the product of frequency and its wavelength.

but why when i answer definition of wave : length between two peak or crust, my answer was wrong.

i means wavelength

u've to mention betweeen two "successive" cresst

if it is GigaHertz it should be 4000000000 not 4000000000000 (asilah)

haha at last aftr 2 yrs someone has noticed this error..btw thnx for the remindr
