We experimentally demonstrate an avoided crossing by coupling two harmonic oscillators. Each harmonic oscillator consists of a mass connected to a stationary wall by a spring. The two harmonic oscillators are coupled by a spring connecting the two masses. An avoided crossing is experimentally demonstrated in two ways: first, by adjusting the spring constant of one oscillator, and then by separately adjusting the mass of the oscillator. In both cases, the adjusted parameter is held constant for the second oscillator. Additionally, we examine the effects from altering the coupling between the two oscillators. These experimental results are shown to be consistent with theoretical predictions.
