The speed of the wave is 18[tex]\frac{m}{s}[/tex].
Explanation:
Given : FREQUENCY (F) = 6Hz
WAVELENGTH(λ) = 3m
If a wave has frequency, f, of 6 Hz, its period, T, is [tex]\frac{1}{6}[/tex] s. The wavelength, λ
, is 3 meters. That means that in the time of one period, the wave travels 3 m.
That means that in the time of one period, the wave travels 3 m.
In General ,
speed =[tex]\frac{distance}{time}[/tex]
In applying this general definition of speed↑to a wave, we have
speed of the wave=wavelength period
Note: we generally use v for speed of a wave. Using the variable names, then that last formula is written
v=λ ×T
so speed of the wave = 3× 6 =18[tex]\frac{m}{s}[/tex]
