The distance between tw o c o n s e c u ti v e loud sounds
depends on distance between two loudspeaker
jarak antara dua bunyi kuat berturutan, x bergantung jarak
antara dua pembesar suara.
The smaller the distance between tw o c o h e r e n t
so u r ce s , the greater distance between tw o c o n s e c u ti v e
ant i nodal l i nes .
Semakin kecil jarak antara dua pembesar suara, semakin
besar jarak antara dua bunyi kuat berturutan
To investigate the relationship between distance between tw o
co h e r e n t so u r ce s and distance between tw o
co n se cu t i ve a n t i n o d a l l i n e s
Untuk mengkaji hubungan antara jarak antara dua pembesar
suara dengan jarak antara dua bunyi kuat berturutan.
Manipulated/dimanipulasi : Distance between two
loudspeakers / jarak antara dua pembesar suara, a
Responding / bergerak balas: distance between tw o
position of loud sounds / jarak antara dua bunyi kuat
berturutan, x
Fixed/ Malar : Frequency /Frekuensi, f
(microphone, cathode ray oscilloscope)
Dua pembesar suara, penjana isyarat audio, pembaris meter.
• The two loudspeakers are placed at a distance, a = 0.4 m
apart.
• Th Th e The positions of two successive loud sounds is determined
and the distance, x, between them is measured with a
meter rule
• The procedure is repeated for the values of a = 0.8 m,1.2 m,
1.6 m and 2.0 m
