This diagram of the electromagnetic spectrum shows how wavelength, frequency and energy are related to one another.. A wavelength of energy that is also called a reciprocal centimeter. Here, h is Planck's constant and c is the speed of light. For example, in an ocean wave approaching shore, shown in the figure, the incoming wave undulates with a varying local wavelength that depends in part on the depth of the sea floor compared to the wave height. 2) Determine the wavelength: λν = c (x) (5.071 x 10 14 s¯ 1) = 3.00 x 10 8 m/s Jahann Balmer in 1885 derived an equation to calculate the visible wavelengths that the hydrogen spectrum displayed. 6.2 Start at the Source: Earth Rotating Around the Sun. wavelength to electron volt page is a free tool enabling online optical calculations OR enter the frequency in gigahertz (GHz) and press "Calculate λ and E" to convert to wavelength.
