relationship between frequency and wavelength

The relationship between frequency and wavelength of an electromagnetic wave is given by the following relation:

𝑐=𝜐𝜆.

Please write a simple Matlab script that shows the relationship between 𝜐 𝑎𝑛𝑑𝜆. Plot 𝜐on the Y-axis and 𝜆on the X-axis. Include units in the axis label, Please make sure that you consider a wide range of the electromagnetic spectrum going from cosmic rays to radio and microwave. Include your Matlab script along with the plot.
