Question
**Question:** Which equation is correct for wave speed? **Options:** 1. \( v = f \lambda \) 2. \( v = \frac{1}{T} \lambda \) 3. Both of these 4. Neither of these It's important to understand the formulas given: 1. \( v = f \lambda \): - Here, \( v \) represents the wave speed. - \( f \) stands for the frequency of the wave. - \( \lambda \) (lambda) is the wavelength. - This formula correctly represents the relationship between wave speed, frequency, and wavelength for a wave. 2. \( v = \frac{1}{T} \lambda \): - In this equation, \( v \) also represents the wave speed. - \( T \) stands for the period of the wave, which is the reciprocal of frequency (\( T = \frac{1}{f} \)). - \( \lambda \) is the wavelength. - This formula is another correct way of expressing wave speed, as the relationship holds true because \( \frac{1}{T} \) is indeed the frequency \( f \). Thus, \( \frac{1}{T} \lambda = f \lambda \). Given this understanding, the correct answer to the question is: 3. **Both of these**
