SPM Physics Question
6. Diagram 6.1 shows a water waves passing through a log that floats in water.
Diagram 6.2 shows a student standing at one corner of a building at B who can hear the sound from a loudspeaker at A.Rajah 6.1 menunjukkan gelombang air bergerak melalui sebatang kayu balak yang terapung di atas permukaan air.
Rajah 6.2 menunjukkan seorang pelajar berdiri pada satu sudut bangunan pada kedudukan B yang masih dapat mendengar bunyi daripada pembesar suara di kedudukan \mathrm{A}.
(b) Referring to Diagram 6.1, what will happen to a floating object that is placed at Merujuk kepada Rajah 6.1, apakah akan terjadi kepada satu objek terapung yang diletakkan pada
(i) \mathrm{P} [1 mark / 1 markah ]
(ii) \mathrm{Q} [1 mark / 1 markah ]
(c) Name one other wave phenomenon that occurs in Diagram 6.1.
Namakan satu fenomena gelombang lain yang berlaku pada Rajah 6.1.[1 mark /1 markah ]
SPM Physics Solution
bi) Vibrates/Oscillates
ii) Stationary
c) Reflection
For (b),
When the wave undergo diffraction due to the obstacles, region P has wave (particles moving up and down about the equilibrium) but region Q does not has wave.
For (c),
Wave will undergo reflection and diffraction when it hits an obstacles like a wall.
Ouhh I seee. Thank you very much!
You are very welcome
