1. a. 1,5
b. 2 cm
c. 1,5 detik
d. 2/3 x 30 cm = 20 cm
e. v = 30/2,25
= 13,33 /detik
f. 2 x 60 : 1,5 = 80
2. λ = V/F
= 340/60
= 6,8 m
3. v = λ/T
= 25/0,02
= 12.500 m/s
4. waktu = s/v
= 8/400
= 0,02 s
f = 1/0,02 x 2
= 100 Hz
5. periode, T = 2 x 0,6 = 1,2 s
frekwensi = 1/T = 1/1,2 = 5/12 Hz
amplitudo = 1/2 x A-C = 1/2 x 20 = 10 cm
