Learn about how waves are measured according to amplitude, wavelength and frequency. The distance between the crests of the waves is the wavelength. Refraction coefficient of water is, say, 1.33, so a ray wavelength in water is now 300nm, which obviously doesn't change it's color. A wave can be described not only by its frequency, then, but also by its length, Figure 2. A wave with a longer wavelength (bottom) has a lower frequency. The relationship between a radio signal’s frequency and its wavelength can be found by the following formula: wavelength = 300 / frequency in MHz. If $\nu_2$ is larger than $\nu_1$ then $\Delta\nu$ will be positive. Useful formulas for RF related conversions Antenna Factor and Gain Calculations dBm to Volts to Watts conversion Magnetic field conversions Field Intensity Calculation Antenna Beamwidth Coverage Calculations VSWR Calculations. Frequency (hertz) is the number of occurrences repeated during a particular period of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. When we look at a light source the colours we see are dictated by the frequency of the light. As the frequency increases, the wavelength decreases. For converting a (small) wavelength interval into a frequency interval, the equation. Frequency and Wavelength Calculator, Light, Radio Waves, Electromagnetic Waves, Physics. Answer: The pendulum takes 5.00 s to complete one cycle, so this is its period, T. The frequency can be found using the equation: f = 0.20 cycles/s. f = c / λ and λ = c / f.
