==================================
✌✌ TERMS & DEFINITIONS ✌✌
✔ FREQUENCY : The number of vibrations or oscillations produced by a vibrating or oscillating body in one second is called its frequency. Its S. I. unit is Hertz.
✔ TIME PERIOD : The time required for one complete oscillation or vibration is called its time period. It is measured in seconds.
✔ WAVELENGTH : It is the length of one wave and it is generally represented by the Greek term, "lambda". Its S. I. unit is metre.
==================================
❄❄❄❄ SOLUTION ❄❄❄❄
Given, Wavelength (W) = 12 m.
Wave velocity (V) = 48 m/s.
Frequency (f) = ?
We know, V = f × W
=> 48 = f × 12
=> 12 f = 48
=> f = (48/12) Hz = 4 Hz. (Answer)
