Answer 2

Calculating the Speed of Wave Propagation

To calculate the speed of wave propagation, we can use the formula:

Speed of wave (v) = frequency (f) × wavelength (λ)

Given: - The number of oscillations (frequency) = 15 - The distance between neighboring wave crests (wavelength) = 2 m

Using the given values, we can calculate the speed of wave propagation:

Speed of wave (v) = frequency (f) × wavelength (λ) Speed of wave (v) = 15 oscillations × 2 m Speed of wave (v) = 30 m

Therefore, the speed of wave propagation is 30 m/s.
