The equation needed is: V=fl Where V is the speed, f is the frequency and l is the wavelength. (the poxy thing won't let me enter a lamba sign) The key bit of information is "in a vacuum"; all waves in a vacuum travel at the same speed, 3x108ms-1. This is more commenly refered to as the speed of light, C. Therefore, f = V / l= C / l = 3x108 / 400x10-9 = 7.5x1014 Hz (Not in standard form that's: 750,000,000,000,000 Hz) (The '/' means divided by)
The answer is 5.0*1014 Hertz.
The wavelength of an electromagnetic wave can be determined using the formula: wavelength = speed of light / frequency. Given the frequency of 1.82x10^18 Hz and the speed of light in a vacuum (3.00x10^8 m/s), we can calculate the wavelength to be approximately 165 nm (nanometers).
The frequency of a wave can be calculated using the formula: frequency = speed of light / wavelength. Given a wavelength of 566 nm (nanometers) and the speed of light in a vacuum (c = 3 x 10^8 m/s), you can convert the wavelength to meters and use the formula to find the frequency.
The formula to calculate wavelength is: wavelength = speed of light/ frequency. Given that the speed of light in a vacuum is approximately 3 x 10^8 m/s, the wavelength of light with a frequency of 6.42 x 10^14 Hz is approximately 467.84 nanometers.
Wavelength x frequency = speed (of the wave), therefore, the frequency is the speed divided by the wavelength. If you are talking about an electromagnetic wave in a vacuum, its speed is approximately 300,000,000 m/s. Also, don't forget to convert the nanometers to meters before doing the division.

The wavelength of light can be calculated using the formula: wavelength = speed of light / frequency. Given a frequency of 6.42 x 10^14 Hz and speed of light in vacuum of 3.00 x 10^8 m/s, the wavelength would be approximately 467.1 nm (nanometers).
Frequency is inversely proportionate to wavelength. That is, f = 1/(lamda) You have frequency, 6.9810214 Hz You want 'lamda'. Re-arranging, you get lamda = 1/f = 1/6.9810214Hz = 0.1432m Then you just need to convert that in to nm, note 1nm = 1*10-9m So (0.1432/10-9) nm
Frequency and wavelength are inversely proportional in a vacuum, following the equation speed = frequency x wavelength. Since the speed of light in a vacuum is constant, knowing the wavelength allows you to determine the frequency of an electromagnetic wave.
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
That number has no units, and just-plain-numbers don't have wavelengths. If you mean that number to have the unit of "Hertz", and to be a frequency of, say, an electromagnetic wave in vacuum, then it's wavelength would be 296.8 nanometers ... an ultraviolet wave.
wavelength. This is because frequency and wavelength have an inverse relationship, meaning as frequency increases, wavelength decreases. This relationship is described by the equation speed = frequency x wavelength, where speed is the speed of light in a vacuum.
Yes, wavelength and frequency are inversely proportional in a vacuum. This means that as wavelength increases, frequency decreases, and vice versa. This relationship is governed by the equation: speed of light = wavelength x frequency.
