Longitudinal waves in a spring have a wavelength of 50mm.The vibrator making them is vibrating at 5 oscillations per second.
Calculate the speed of the waves.
To calculate the speed of the waves, we need to use the formula:
Speed = Wavelength x Frequency
First, we need to convert the wavelength from millimeters to meters since the speed is usually measured in meters per second.
Wavelength = 50mm = 50/1000m = 0.05m
Now we can calculate the speed:
Speed = 0.05m x 5Hz = 0.25 m/s
Hence, the speed of the waves in the spring is 0.25 m/s.
