Wavelength (λ) is the measurement of the distance between two high peak points. It is inversely proportional to frequency, which refers to the number of wave cycles per second. Frequency (hertz) is the number of occurrences repeated during a particular period of time. Given below wavelength frequency formula page to convert the values from λ to hertz. Also, you can navigate to the online calculator provided below to manually calculate the wavelength of light.
Wavelength frequency formula is defined as speed of light ((3 x 108) / frequency). In the above given online calculator, you can calculate λ in various measurements such as centimeter, meter, decimeter, kilometer and so on.
