1. The problem statement, all variables and given/known data

The atomic mass of tellurium is 2.12×10-25 kg, and the frequency, 7.53×1012 Hz. What is the effective force constant that connects the two atoms?

2. Relevant equations

Have no idea

3. The attempt at a solution

I am lost with this problem, we havn't learned it in the lectures.

Hi dal11!

Since this is in "introductory physics", I think that they want you to assume that there's an invisible spring with a mass of 2.12×10-25 kg at either end and an oscillation frequency of 7.53×1012 Hz, and to find the spring constant.

Ok that makes sense ;), but I am still don't know how to do that given this information.

do you know what a spring constant is?

or what Hooke's law is? or what shm (simple harmonic motion) is?

do you know any equations relating to springs or to shm?
