To find the wavelength (λ) when you only have the frequency (ν), you can use the equation:
wavelength (λ) = speed of light (c) / frequency (ν)
The speed of light is a constant value, approximately 3.00x10^8 meters per second (m/s). Plugging in this value:
wavelength (λ) = 3.00x10^8 m/s / frequency (ν)
By dividing the speed of light by the frequency, you can determine the corresponding wavelength.
