Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
The wavelength is 430 nm, approx.
The answer is 5.0*1014 Hertz.
Speed (of a wave) = frequency x wavelengthTherefore, you have to: * Convert the wavelength to meters. * Divide the speed of light - which is 300 million meters/second - by this wavelength. The answer will be in Hz.
Ultraviolet light has a wavelength below 400 nanometers, infrared;s wavelength is less than 700 nanometers or so. Frequency is inversely proportional to wavelength, so ultraviolet light has a much a much higher frequency than infrared.
Wavelength is speed, of light, in this case, divided by frequency. 3 x 108 meters per second divided by 6.82 x 1014 Hertz is 0.4 micrometers.
When the wavelength of a wave increases, the frequency decreases. When the wavelength decreases, the frequency decreases. These two values are said to be inversely proportional. Here is the equation for velocity of a wave: v = f λ where v = velocity (usually 3.0 x 108 meters/second2, which is the speed of light) f = frequency (usually in Hertz or 1/seconds) λ = wavelength (usually in nm or nanometers)
Violet light has a wavelength of 413 nanometers.
um it would be (approximately) the same wavelength of the green light in nanometers instead of any other color wavelength it would nanometers.
Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.
Violet light is 375 nanometers.
Frequency is in cycles per unit time Wavelength is in length per cycle To convert between the two you need the speed of the wave - which for light is the speed of light - which is given in length per unit time Frequency = Speed of light/Wavelength For a wavelength of 469 nanometers Frequency is 639 Terahertz (THz) or 639,000 Gigahertz (GHz) ... rounded to 3 significant digits since the wavelength is only given to 3 significant digits
speed of light in meters per second / wavelength in meters = frequency in Hz299 792 458m/s / 0.000000690m = 434481823188406Hz = 434481823188.4KHz =434481823.2MHz = 434481.8GHZ = 434.5THz
The frequency is f= c/w= 3e8/265e-9 = 1.132e15 hertz.
