Question

You're making waves in a pool of water by pushing the water with your finger. The distance between the crests of the waves is 10 cm. Your finger moves up and down 4 × per second. The top of the waves reaches 2 cm above the surface of the water. The entire pool of water is 50 cm across. What is the wavelength of the waves?

A. 50 cm
B. 5 cm
C. 2 cm
D. 10 cm

Answer 1

The wavelength of the waves created in the swimming pool is 0.400 m.

Step-by-step explanation:

The wavelength of the waves can be calculated using the formula: wavelength = wave speed / frequency. In this case, the wave speed is 0.800 m/s and the frequency is 2 Hz. So, the wavelength will be 0.800 m/s / 2 Hz = 0.400 m. Therefore, the wavelength of the waves is 0.400 m.
