Multiple Choice
Apabila membandingkan dua gelombang yang ditunjukkan, bagaimanakah gelombang hijau berbeza daripada gelombang hitam?
When comparing the two waves that are shown, how would Wave A (green wave) differ than Wave B (black wave)?
Kedua-dua gelombang mempunyai amplitude yang sama, tetapi gelombang hitam mempunyai frekuensi yang lebih rendah.
Both have the same amplitude, but black wave has a lower frequency.
Kedua-dua mempunyai amplitud yang sama, tetapi gelombang hijau mempunyai frekuensi yang lebih rendah.
Both have the same amplitude, but green wave has a lower frequency.
Kedua-duanya mempunyai frequensi yang sama, tetapi gelombang hijau menghasilkan bunyi yang lembut.
Both have the same frequency, but green wave is a softer sound.
Kedua-duanya mempunyai frekuensi yang sama, tetapi gelombang hitam menghasilkan bunyi yang lebih lembut.
Both have the same pitch, but black wave produces a softer sound.

Multiple Select
Pilih pernyataan yang benar mengenai kelangsingan bunyi...TP3
Kelangsingan digambarkan sebagai KEKUATAN bunyi
Frekuensi bunyi, f adalah bilangan ayunan yang terjadi dalam satu saat. Frekuensi diukur dalam unit Hertz (Hz)
Kelangsingan bergantung pada frekuensi
Semakin tinggi frekuensi bunyi, semakin tinggi kelangsingan bunyi
