AP Physics B covers fundamental concepts in physics, including mechanics, thermodynamics, and waves, preparing students for college-level physics courses.
Waves are disturbances that transfer energy through space or matter. They come in two main types: mechanical (like sound) and electromagnetic (like light).
Sound is a mechanical wave that travels through air (or other media). It needs a medium to move—no sound in space!
Waves explain musical instruments, cell phone signals, and even how we see and hear.
Plucking a guitar string creates sound waves you can hear.
Ocean waves carry surfers to shore.
Waves carry energy and information, making sound, music, and communication possible.
