A vibrator causes water ripples to travel across the surface of a tank. The wave travels 50cm in 20s and the distance between successive crests is 5cm. Calculate the frequency of the vibrator
A
5Hz
B
6Hz
C
5.2Hz
D
25Hz
Ask EduPadi AI for a Detailed Answer
Correct Option: A
| V = | distance
time | = | 50 cm
25 | = | 25 cm/s |
V = fλ
hence,
| f | = | V.λ |
| = | 25
5 | = | 5Hz |
f = 5Hz
