Answer:
400 m/s
Explanation:
From the question;
- The frequency of the wave is 200 Hz
- Wavelength of the wave is 2 meters
We are required to calculate the speed of the wave;
- We need to know that the speed of the wave is calculated by multiplying frequency by the wavelength of the wave.
- That is, speed = wavelength × frequency
Speed of the wave = 200 Hz × 2 m
= 400 m/s
- Thus, the speed of the wave is 400 m/s
