To calculate the wavelength of a wave, you can use the wave equation:
\[ \text{Wavelength} (\lambda) = \frac{\text{Wave Speed} (v)}{\text{Frequency} (f)} \]
Given:
- Wave Speed \( v = 0.315 , \text{m/s} \)
- Frequency \( f = 50 , \text{Hz} \)
Now, plug the values into the formula:
\[ \lambda = \frac{0.315 , \text{m/s}}{50 , \text{Hz}} \]
Calculating this gives:
\[ \lambda = \frac{0.315}{50} = 0.0063 , \text{m} \]
So, the wavelength is:
\[ \lambda = 0.0063 , \text{m} , \text{or} , 6.3 , \text{mm} \]
