C Frekuensi gelombang tuju kurang daripada 5 Rajah 5 menunjukkan perambatan gelombang air melalui
gelombang pantulan. / The frequency of the incident blok perspek di dalam tangki riak. / Diagram 5 shows water
wave is less than the reflected wave. wave propagating through a perspex block in a ripple tank.
D Sudut gelombang tuju lebih besar daripada sudut
gelombang pantulan. / The angle of incident wave is
greater than the angle of reflected wave. Blok perspek
Perspex block

A spring is pushed forwards and backwards. menyumbang kepada kejadian gempa bumi, gelinciran
tanah, letupan gunung berapi dan runtuhan salji. Didapati
bahawa panjang gelombang, λ tsunami semakin pendek
D Spring ditolak ke atas dan ke bawah. apabila menghampiri pantai seperti yang ditunjukkan
A spring is pushed up and down. dalam Rajah 6.
A tsunami is a series of water wave caused by the displacement
of a large volume of water, usually occurs in ocean or large
lake. This displacement of water is usually contributes to
earthquakes, landslides, volcanic eruptions and avalanche.
It is found that the wavelength, λ of the tsunami becomes
