Physic Prelim - Careless.
Well, physic is over. DID A MAJOR CARELESS MISTAKE!!!
The question goes smth like this: 9 balls are linked together with each other at regular interval of 1.00m using strings. The balls are placed on the sea and a wave comes. Ball 9 starts moving after ball1 goes thrrough one complete ocsilation.(donno how to spell). I was careless enough to write 4.5m as the answer for the wavelength. Ahhhhhhhhhh!!! The answer should be 8.0m. Also, we were asked to plot the the wave. Because i was thinking that the wavelength is 9.0m, i drew the wave through the "x-axis" at the 4.5m mark. Ah.... a few marks gone just like that. Too ultra careless!!! Urgh...
