WAVE / GELOMBANG

1. Diagram 1.1 shows the pattern of some water waves before and after passing through a gap.
The experiment is repeated by using water waves of a different wavelength which pass through the
same gap, and the resulted pattern is shown in diagram 1.2.
Rajah 1.1 menunjukkan corak beberapa gelombang air sebelum dan selepas melalui halangan.
Eksperimen ini diulang menggunakan gelombang air yang berlainan panjang gelombang yang
melalui halangan yang sama. Keputusan corak ditunjukkan pada Rajah 1.2.

(a) What is meant by wavelength?
Apakah maksud panjang gelombang?
