Draw schematics of the configurations shown but replace the molecular bonds with springs: each bond has a spring constant (kn) and each molecule has a mass (mn). Describe how you might develop a model for calculating the resonant frequency for each of the three molecular configurations (you don’t have to work out the math!). This model describes “acoustic phonons”.
