Wave A will be faster than the wave B because [tex]V_A > V_B[/tex]
The frequency of the wave is defined as the cycle completed by the wave per second.
Now it is given in the question:
Frequency of wave A = 250 hertz
The wavelength of wave A= 30 cm
Frequency of wave B = 260 hertz
The wavelength of wave B= 25 cm
Now for finding which wave is faster we will calculate the velocity of the wave.
For Wave A
[tex]V_A=f\times\lambda=250\times 30=7500\ \frac{cm}{s}[/tex]
For wave B
[tex]V_B=f\times\lambda=260\times 25=6500\ \frac{cm}{s}[/tex]
We can see that the velocity of wave A is higher than the velocity of wave B.
Thus wave A will be faster than the wave B because [tex]V_A > V_B[/tex]
