12. v = f x L ; 0,2 kHz --> 200 Hz 100 = 200 x L 100/200 = L L = 0,5 m --> 50 cm
13. 2 getaran = 4 m 20 m = 4 sekon jadi, supaya mendapat jawaban, dikali 5 2 getaran x 5 = 4 m x 5 10 getaran = 20 m, otomatis 10 getaran = 4sekon f = n/t f = 10/4 = 2,5 Hz
14. v = f x L 20 = f x 5 20/5 = f f = 4 Hz (gaada jwban ntah antara gue salah jwb, ato salah opsinya)
f = 2/1 = 2
12. v = f x L ; 0,2 kHz --> 200 Hz
100 = 200 x L
100/200 = L
L = 0,5 m --> 50 cm
13. 2 getaran = 4 m
20 m = 4 sekon
jadi, supaya mendapat jawaban, dikali 5
2 getaran x 5 = 4 m x 5
10 getaran = 20 m, otomatis 10 getaran = 4sekon
f = n/t
f = 10/4 = 2,5 Hz
14. v = f x L
20 = f x 5
20/5 = f
f = 4 Hz (gaada jwban ntah antara gue salah jwb, ato salah opsinya)
15. T = t/n
T = 8/4 = 2 sekon
jgn percaya ama no 14 dlu ya... ;) moga m'bantuu
