A man standing on the seashore determined that there were 2 meters between successive ridges and 6 ridges in 1 minute past him. Wave propagation speed.
To find the speed of propagation of these waves, we will use the formula: V = λ / T = λ / (t / n) = λ * n / t.
The values of the variables: λ – the length of the indicated waves (λ = 2 m); n is the number of wave crests passing by a person (n = 6 crests); t is the duration of observations (t = 1 min = 60 s).
Calculation: V = λ * n / t = 2 * 6/60 = 0.2 m / s.
Answer: The speed of propagation of these waves is 0.2 m / s.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
