Final answer:
The speed of the waves in the puddle is 0.30 meters per second, calculated using the frequency of 2 Hz and the wavelength of 0.15 m.
Step-by-step explanation:
To calculate the speed of the waves in a puddle that are 0.15 m apart and made by tapping the water surface twice each second, we can use the formula for the speed of a wave (v), which is the product of its frequency (f) and wavelength (λ). Given that the frequency of tapping (which is the same as the frequency of the waves) is 2 Hz, and the distance between the waves (the wavelength) is 0.15 m, the speed can be calculated as follows:
v = f λ
v = 2 Hz × 0.15 m
v = 0.30 m/s
The speed of the waves in the puddle is 0.30 meters per second.
