Answer:
"332.8 m/s" is the right solution.
Explanation:
The given values are:
Wavelength,
[tex]\lambda=0.65 \ m[/tex]
Frequency,
[tex]f = 512 \ Hz[/tex]
As we know,
⇒ [tex]Speed=Frequency\times Wavelength[/tex]
or,
⇒ [tex]V=f\times \lambda[/tex]
By putting the given values in the above relation, we get
⇒ [tex]=512\times 0.65[/tex]
⇒ [tex]=332.8 \ m/s[/tex]
