calculate the speed of waves in a puddle that are 0.15m apart and made by tapping the water surface twice each second
To calculate the speed of waves in a puddle, we need to determine the wavelength and the frequency of the waves.
Given:
Wavelength (λ) = 0.15m
Frequency (f) = 2 taps/second
The speed (v) of a wave can be calculated using the formula:
v = λ * f
Substituting the given values into the formula:
v = 0.15m * 2 taps/second
To continue the calculation, we need to convert the taps/second into Hz (Hertz). Since 1 Hz is equal to one cycle per second, we can conclude that 1 tap/second equals 1 Hz. Therefore, the frequency in this case remains the same:
v = 0.15m * 2 Hz
Now we can calculate the speed:
v = 0.30 m/second
Therefore, the waves in the puddle have a speed of 0.30 m/second.
To calculate the speed of waves in a puddle, we first need to determine the wavelength (λ) and the frequency (f) of the waves.
The wavelength (λ) is the distance between two consecutive wave crests or troughs. In this case, the waves are 0.15m apart, so the wavelength is 0.15m.
The frequency (f) is the number of waves passing a given point per second. In this case, the water surface is tapped twice each second, so the frequency is 2 Hz (2 waves per second).
The speed of a wave can be calculated using the formula:
speed = wavelength × frequency
Plugging in the values we have:
speed = 0.15m × 2 Hz
Now we can calculate the speed of the waves:
speed = 0.30 m/s
Therefore, the waves in the puddle have a speed of 0.30 m/s.
distance = speed * time
distance = .15 m
time = 0.5 second
