|
resonance
|
|
|
refraction

Explanation:
Detailed explanation-1: -Since the incoming sound waves share the same natural frequency as the second tuning fork, the tuning fork easily begins vibrating at its natural frequency. This is an example of resonance-when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion.
Detailed explanation-2: -The vibration of a tuning fork is an example of periodic motion.
Detailed explanation-3: -The tuning fork is the object that forced the air inside of the resonance tube into resonance. As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube.
