frekuensi paling kecil dihasilkan oleh benda... pliss jangan goblogg komentar dan jawaban nya

Benda P:
n = 60
t = 30 s
f = n/t
f = 60/30 = 2 Hz

Benda Q:
n = 80
t = 50 s
f = n/t
f = 80/50 = 1,6 Hz

Benda R:
n = 100
t = 40 s
f = n/t
f = 100/40
f = 2,5 Hz

Benda S:
n = 120
t = 25 s
f = n/t
f = 120/25
f = 4,8 Hz

Frekuensi terkecil: Benda 'Q'
