Sound

Resonance happens when a sound wave matches the natural frequency of an object and causes the object to vibrate

The similarities of Constructive and Destructive interferences are they both change the amplitude of the wave

A different medium changes the speed of sound if its a gas, liquid, or a solid

Steel is a material that really absorbs sound waves such as here with the train tracks

Sound Waves

Science

A different temperature changes the speed of sound when the air is warmer it travels faster and the opposite for colder air.

An echo is when matter reflects sound waves

The differences of constructive and destructive interferences are constructive make a larger amplitude and destructive make a smaller amplitude

A sonic boom happens when let's say jet plane is moving faster than the speed of sound it can produce a very loud sound

Resonance can occur in brdges too. Because resonance could cause a bridge to collapse, engineers plan their designs carefully. Even rhythmic marching can create resonance
