A sinosoidal wave whose has period 0.20 s and wavelength 2.0 m, its speed will be "10 m/s".
Wavelength and Frequency
According to the question,
Wavelength, π = 2m
Period = 0.20 s
We know the relation,
→ Period = [tex]\frac{1}{Frequency(f)}[/tex]
or,
→ f = [tex]\frac{1}{Period}[/tex]
By substituting the value,
= [tex]\frac{1}{0.2}[/tex]
= 5 Hz
hence,
The wave speed will be:
→ v = Wavelength × frequency
= 5 × 2
= 10 m/s
Thus the approach above is correct.
