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
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
The speed of a wave is calculated by multiplying its wavelength by its frequency. In this case, the speed would be 340 m/s.
If the frequency is multiplied by 1.5, the wavelength will decrease by a factor of 2/3. This is because wavelength and frequency are inversely proportional to each other in a wave's speed equation (speed = wavelength × frequency).
velocity=wavelength*frequency. You do the math
Just use the relationship: speed (of the wave) = frequency x wavelength. If the frequency is in hertz (cycles/second), and the wavelength in meters, then of course the speed will be in meters/second.
If the frequency is doubled, the wavelength of the wave will be halved. This is because the speed of the wave remains constant, so as frequency increases, the wavelength decreases to maintain that constant speed.
Frequency = (speed)/(wavelength) = 10/20 = 1/2
1). Frequency = (speed) / (wavelength)2). Wavelength = (speed) / (frequency)3). Speed = (frequency) x (wavelength)Use #3:Wavelength = (35 cm/s) / (25 Hz) = 1.4 cm
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
