Hertz is the unit of frequency in the International System of Units (SI). It measures cycles per second.
Imagine you're watching your favorite drummer play. The number of times they hit their drum each second can be measured in hertz - if they hit it 60 times per second, that's 60 Hz!
Megahertz (MHz): This represents one million hertz or million cycles per second.
Gigahertz (GHz): This stands for billion hertz or billion cycles per second.
Periodic motion: This refers to any motion that repeats at regular time intervals and can be measured using hertz.
