A man standing on the seashore determined that the distance between successive wave crests is 8 m and 45 wave crests pass by him in 1 minute. What is the propagation speed of waves?
To calculate the value of the propagation velocity of these waves, we apply the formula: V = λ / T = n * λ / t.
Variables: n – number of wave crests (n = 45 crests); λ is the specified wavelength (λ = 8 m); t is the duration of observations (t = 1 min = 60 s).
Calculation: V = n * λ / t = 45 * 8/60 = 6 m / s.
Answer: These waves propagate at a speed of 6 m / s.
