Question

Problem 1: a ball on the surface of a pool bobs up and down due to the waves formed in the pool. the water waves have a wavelength of 1.2 meters, and they pass the ball with a frequency of 3 hertz. what is the speed of the waves? part b: from the library, select the general equation to solve for the speed of a wave. then click done.

Answer 1

The speed of the water waves is calculated using the equation v = λ * f, resulting in a wave speed of 3.6 meters per second when the wavelength is 1.2 meters and the frequency is 3 hertz.

Step-by-step explanation:

To find the speed of the water waves, we use the general equation for the speed of a wave, which is the product of its wavelength (λ) and its frequency (f). This equation is given by v = λ * f. Given that the wavelength is 1.2 meters and the frequency is 3 hertz, we can calculate the speed (v) as follows:

v = 1.2 m * 3 Hz = 3.6 m/s.

Therefore, the speed of the waves is 3.6 meters per second (m/s).
