A taut wire has a wave with a wavelength of 4.5 meters and a frequency of 100 hertz. What is the speed of the wave in the wire
A) 450 m/s
B) 4500 m/s
C) 0.045 m/s
D) 22.2 m/s
v = f*w
Thank you
The speed of a wave can be calculated using the formula:
Speed = Wavelength x Frequency
Given that the wavelength is 4.5 meters and the frequency is 100 hertz, we can substitute these values into the formula:
Speed = 4.5 meters x 100 hertz
Calculating the product:
Speed = 450 meters/second
Therefore, the speed of the wave in the wire is 450 m/s.
Thus, the correct answer is:
A) 450 m/s
To find the speed of the wave in the wire, we can use the equation:
Speed = frequency x wavelength
Given:
Frequency = 100 Hz
Wavelength = 4.5 meters
Now we can plug in these values into the equation to find the speed:
Speed = 100 Hz x 4.5 meters
Speed = 450 meters/second
Therefore, the speed of the wave in the wire is 450 m/s.
So the correct answer is option A) 450 m/s.
