wavelength = speed of light/frequency so as the frequency decreases, the wavelength increases.
speed of wave = frequency * wavelength if frequency is doubled wavelength must be halved 8=4*2 8=8*1
Wavelength = 1/frequency. If you double the frequency, the wavelength drops to half.
speed = freq. X wavelength Hence frequency and wavelength are inversely related when the speed is same. So if the frequency is doubled, then wavelength becomes half of the initial length.
Speed = wavelength x frequency, so wavelength = speed / frequency. Therefore, the wavelength is inversely proportional to the frequency. Double the frequency means half the wavelength.
If the frequency becomes double what it was, then the wavelength becomes 1/2 of what it was.
frequency is also doubled
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).
The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)
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
