medium
resonance
When vibrations travel through an object's natural frequency, resonance occurs. This causes the amplitude of the vibrations to increase, potentially leading to structural damage or failure if it exceeds the object's capacity to withstand stress. Resonance can also be harnessed in beneficial ways, such as in musical instruments that produce clear and loud sound.
When two objects vibrate at the same frequency, they resonate with each other, causing a stronger vibration. This resonance amplifies the vibrations, making them more noticeable and powerful.
Sound is created by the vibration of air. The faster the vibration, the higher the sound. Smaller objects can vibrate faster than larger objects (of the same kind) and therefore have a higher pitched sound.
Absolutely not! Glass, for example (every wine glass has a different natural frequency), can be broken by a frequency that matches its own but nearby objects aren't affected by the same frequency.

resonance
Forced vibration occurs when an object is made to vibrate by another vibrating object. Resonance occurs when frequency of a vibration forced on an object matches the objects natural frequency Appyed force to a vibrating system and then removing the source energy.

density that is dependant on mass
When two objects vibrate at the same frequency, they resonate with each other, causing a stronger vibration. This resonance amplifies the vibrations, making them more noticeable and powerful.

Because all the objects have a natural frequency
Sound is created by the vibration of air. The faster the vibration, the higher the sound. Smaller objects can vibrate faster than larger objects (of the same kind) and therefore have a higher pitched sound.
Every object has a unique natural frequency of vibration. Vibration can be induced by the direct forcible disturbance of an object or by the forcible disturbance the medium in contact with an object (e.g. the surrounding air or water). Once excited, all such vibrators (i.e., vibratory bodies) become generators of sound waves. For example, when a rock falls, the surrounding air and impacted crust undergo sinusoidal oscillations and generate a sound wave.Vibratory bodies can also absorb sound waves. Vibrating bodies can, however, efficiently vibrate only at certain frequencies called the natural frequencies of oscillation. In the case of a tuning fork, if a traveling sinusoidal sound wave has the same frequency as the sound wave naturally produced by the oscillations of the tuning fork, the traveling pressure wave can induce vibration of the tuning fork at that particular frequency.Mechanical resonance occurs with the application of a periodic force at the same frequency as the natural vibration frequency. Accordingly, as the pressure fluctuations in a resonant traveling sound wave strike the prongs of the fork, the prongs experience successive forces at appropriate intervals to produce sound generation at the natural vibrational or natural sound frequency. If the resonant traveling wave continues to exert force, the amplitude of oscillation of the tuning fork will increase and the sound wave emanating from the tuning fork will grow stronger. If the frequencies are within the range of human hearing, the sound will seem to grow louder. Singers are able to break glass by loudly singing a note at the natural vibrational frequency of the glass. Vibrations induced in the glass can become so strong that the glass exceeds its elastic limit and breaks. Similar phenomena occur in rock formations.All objects have a natural frequency or set of frequencies at which they vibrate.
