The speed is (2 times the frequency) meters per second.
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
If the frequency becomes double what it was, then the wavelength becomes 1/2 of what it was.
Wavelength = speed/frequency = 120/6,000 = 2 centimeters
Speed = (frequency) x (wavelength) = (12 per sec) x (2 meters) = 24 m/sec
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
340 m/s
Assuming that the wavelength remains constant, the velocity of the rope will also double if the frequency is doubled. This can be seen in the word equation below: speed = frequency x wavelength If we assume that wavelength is a constant...let wavelength = 1 speed = frequency therefore... 2 x frequency = 2 x speed
Frequency = (speed)/(wavelength) = 10/20 = 1/2
Wavelength = speed/frequency = 2/15 Hz = roughly 0.133... Hz.
Wavelength = speed/frequency = 120/6,000 = 2 centimeters
If the frequency becomes double what it was, then the wavelength becomes 1/2 of what it was.
Speed = (frequency) x (wavelength) = (12 per sec) x (2 meters) = 24 m/sec
Speed = (wavelength) x (frequency) = (2 x 6) = 12 meters per second.That's the wave's speed. "Velocity" is something different, not just a wordto use when you mean "speed" but you want to sound more technical.
If the frequency is doubled then the wave length and period will be halved because in the same time that the original wave occurred, you will now see 2 waves. .here is NO change in its its speed.
1). Frequency = (speed) / (wavelength)2). Wavelength = (speed) / (frequency)3). Speed = (frequency) x (wavelength)Use #3:Wavelength = (35 cm/s) / (25 Hz) = 1.4 cm
