See the answer. Determining wave frequency from a graph. Share 1. What is the wavelength of the wave above? If you're talking about a graph that looks like a sine graph, it's the distance between two amplitudes (from left to right) of the same side (ex. This is apparently a thing now that people are writing exams from home. 2.) Wiki User Answered . Understanding spectra with graphs. Note which scenario has greater amplitude and which has a higher frequency. To find the wavelength, look at where the graph crosses the y axis; notice that the wave is descending and the value is 7 cm. Waves. For the relationship to hold mathematically, if the speed of light is used in m/s, the wavelength must be in meters and the frequency in Hertz. Wavelength: λ: meter: m: λ = ν / f: Wave speed: ν: meter per second: m/s: ν = λ × f Speed of sound: c: meter per second: m/s: c = λ × f What kind of graph?
