Bandwidth is the output of some light source, the width of the frequency range which can be transmitted by some element, the gain bandwidth of an optical amplifierthe width of the range of some other phenomenon. It's values may be specified in terms of frequency or wavelength.
The relation between cut off frequency (fc) and band width is as follows: fc=Q*B.W where Q=(fL*fH)^1/2/(fH-fL) Q is quality factor. fL is low frequency. fH is high frequency.
For horizontal antennas operating below 30 MHz the optimum height is half a wavelength, so the height in metres would be 149.9/Frequency in MHz.
Its resonant frequency is where its length is half a wavelength, so for 100 MHz the wavelength is 3 metres and a 1.5-metre long dipole is resonant. A dipole antenna can be used for many applications within a band of 10-20% around the resonant frequency.
300nm is the "wavelength". Wavelength and frequency are related by the following equation: λ = v / f Where λ (gamma) is the wavelength, v is the speed of the wave (typically c, the speed of light (3×10^8 m/s)), and f is the frequency. So f = v / λ. So a 300nm wave, (λ = 300*10^-9 m) has a frequency of (3e8 / 300e-9) = 1e15Hz or 1,000THz. 500nm: (3e8 / 500e-9) = 6e14Hz or 600THz. See link.
Speed = (frequency) times (wavelength) Frequency = (speed) divided by (wavelength) Wavelength = (speed) divided by (frequency)
frequency = speed of light/wavelength
Use the relation: speed = frequency x wavelengthUse the relation: speed = frequency x wavelengthUse the relation: speed = frequency x wavelengthUse the relation: speed = frequency x wavelength
For any wave, frequency x wavelength = speed of the wave.
Wavelength = (speed) divided by (frequency) Frequency = (speed) divided by (wavelength) Speed = (frequency) times (wavelength)
The shorter the wavelength is, the higher the frequency will be and the longer the wavelength is, the lower the frequency will be.
For a single wave: Speed = (frequency) x (wavelength) Frequency = (speed) / (wavelength) Wavelength = (speed) / (frequency)
Wavelength = wave speed/frequency Frequency = wave speed/wavelength (Wavelength) x (Frequency) = Wave speed
Wavelength and frequency are inversely proportional.
Speed = frequency x wavelengthThis is true for all waves, sound waves as well as electromagnetic waves.
Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m
Wave speed = (Wavelength) times (frequency).
