lambda=c/nu The speed of light, c, equals the wavelength, lambda (pronounced lambda), times the frequency, nu, (pronounced noo). wavelength, distance between corresponding points of two consecutive waves.
It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. As the speed of light is constant, if you increase the frequency, the wavelength must decrease to maintain this equation and vice versa.
From the above information, finally, we can conclude that these light waves are electromagnetic waves that are visible.

Frequency has a unit of "1/s", which means 1 cycle per second. It is usually given as 3.00xx10^8 m/s or 3.00xx10^10 cm/s rounded to three significant figures. Frequency is related to wavelength by λ = c / ν, where c, the speed of light, is 2.998 x 10 8 m s -1.
The reason for this is that the wavelength of green light is shorter that the wavelength of red. If the source of a wave is stationary, the space between each ring (the wavelength) should be constant, and the rings should appear completely circular.An observer located anywhere around the source will record the wave arriving at her location with a wavelength equal to the wavelength as it was emitted.
When wavelength is measured in metres, 1/λ represents the number of waves of the wave train to be found in a length of one metre or, if measured in centimetres, the number in one centimetre.
