Question

complete wavelength (0.5λ) at 50cm. therefore, a complete wavelength is 100cm. formula: 0.5λ=50cm λ=100cm multiplying the frequency (f) by the wavelength (λ) formula: v=fλ v= 0.66 cm/s

the wave in this
demonstration is a complete
wavelength at 50cm.
therefore, a complete
wavelength is 50cm.
formula: 1λ=50cm
λ=50cm
the speed (v) of a
wave is calculated by
multiplying the
frequency (f) by the
wavelength (λ).
formula: v=fλ
v=________ cm/s

Explanation:

Step1: Identify given values

We know the formula for wave speed is \( v = f\lambda \). From the table, wavelength \( \lambda = 50 \, \text{cm} \). We assume the frequency \( f = 1 \, \text{Hz} \) (from the "frequency" column where it says frequency \( f \) is 1).

Step2: Substitute into formula

Substitute \( f = 1 \, \text{Hz} \) and \( \lambda = 50 \, \text{cm} \) into \( v = f\lambda \).
\( v = 1 \times 50 \)

Step3: Calculate the result

\( v = 50 \, \text{cm/s} \)

Answer:

50
