Eksperimen 1. Tempoh bandul ringkas / Period of a simple pendulum
Experiment 2. Panjang gelombang air / Wavelength of water wave

Eksperimen 1. Tempoh Bandul Ringkas 2. Panjang Gelombang Air
Experiment Period of A Simple Pendulum Wavelength of Water Wave
Tempoh / Masa ayunan bergantung pada Panjang gelombang dipengaruhi oleh frekuensi.
Inferens panjang bandul. Wavelength is influenced by frequency.
Inference The period / time of oscillation depends on
the length of the pendulum.

Tempoh meningkat dengan panjang / Semakin panjang Semakin tinggi frekuensi, semakin pendek panjang UNIT 1
bandul ringkas, semakin panjang tempoh ayunan. gelombang.
Hipotesis The period increases with length / The longer the The higher the frequency, the shorter the wavelength.
Hypothesis
pendulum, the longer the period of oscillation.

Mengkaji hubungan antara panjang dan tempoh Mengkaji hubungan antara frekuensi dan panjang
Tujuan ayunan bandul ringkas. gelombang bagi gelombang.
Aim To investigate the relationship between the length and To investigate the relationship between frequency and
the period of oscillation for a simple pendulum. wavelength of a wave.
