Solution

Step 1-Given,
$T = 5 \times 10^{- 3} s e c o n d s, λ = 50 c m = 0.5 m .$
Where, T is the time period, v is the velocity of the wave, and f is the frequency.
Step 2- Finding the frequency of the wave.
$f = \frac{1}{T} = \frac{1}{5 \times 10^{- 3}} = 200 H z .$
Step 3- Finding the speed of the wave.
$v = f λ = 200 \times 0.5 = 100 m / s .$
Thus, the answer for the frequency is $200 H z$ and the velocity of the wave is $100 m / s$ .
