The video explains how sound vibrations can break glass by matching its resonance frequency. It discusses the science behind resonance, how to find a glass's resonance frequency, and the conditions needed to break it with sound. Safety precautions are emphasized, and practical tips are provided for safely attempting this experiment using microphones and amplifiers.

What is the term used to describe the natural frequency at which a material tends to vibrate?

• Vibrational frequency

• Harmonic frequency

• Resonance frequency

• Amplitude frequency

Which of the following factors makes a glass more likely to shatter?

• Being new and expensive

• Being old and cheap

• Being made of plastic

• Being thick and flawless

What is the approximate frequency, in hertz, that is most likely to match the resonance frequency of a typical glass?

• 1000 hertz

• 500 hertz

• 200 hertz

• 1500 hertz

What is the minimum decibel level required to potentially break a glass using sound?

• 100 decibels

• 125 decibels

• 75 decibels

• 50 decibels

What is a recommended method to safely attempt breaking glass with sound?

• Using a microphone and amplifier

• Holding the glass in your hand

• Standing very close to the glass
