d)speed

Explanation:

Question 12

Step1: Recall wave equation

The wave equation is \( \text{Velocity} = \text{wavelength} \times \text{frequency} \). So the missing term is frequency.

Step1: Identify formula

Use the wave equation \( v=\lambda\times f \), where \( \lambda = 6\,\text{m} \), \( f = 2\,\text{Hz} \).

Step2: Substitute values

\( v = 6\,\text{m} \times 2\,\text{Hz} = 12\,\text{m/s} \).

Step1: Recall period - frequency relation

The formula relating period (\( T \)) and frequency (\( f \)) is \( T=\frac{1}{f} \), so the missing term is frequency.

Answer:

frequency
