Question

An ocean wave observed to have a wavelength of 6m and a period of 2s, what is the wave speed?

A) 1.5 m/s
B) 2 m/s
C) 3 m/s
D) 6 m/s

Answer 1

The wave speed can be calculated by multiplying the wavelength by the frequency. In this case, the wave speed is 3 m/s. Therefore, the wave speed is 6 meters divided by 2 seconds, resulting in 3 m/s (C).

Step-by-step explanation:

The wave speed can be calculated by multiplying the wavelength (λ) by the frequency (f). The formula for wave speed (v) is v = λ * f.

In this case, the wavelength is given as 6m and the period (the inverse of frequency) is given as 2s. To find the frequency, we can use the formula f = 1 / T, where T is the period. So, f = 1 / 2s = 0.5 Hz.

Using the formula v = λ * f, the wave speed is v = 6m * 0.5 Hz = 3 m/s.

The speed of a wave can be calculated using the formula velocity (v) = wavelength (λ) / period (T). Given an ocean wave with a wavelength of 6 meters and a period of 2 seconds, the wave speed can be found by dividing the wavelength by the period. Therefore, the wave speed is 6 meters divided by 2 seconds, resulting in 3 m/s.
