HERTZ IS THE SI UNIT OF WAVE FREQUENCY, WHERE 1 HERTZ EQUALS 1 WAVE PASSING A FIXED POINT PER SECOND.

MEDIUM IS THE NAME FOR THE MATTER THAT WAVES CAN TRAVEL THROUGH.

THE WAY A PERSON PERCEIVED THE FREQUENCY OF A SOUND, WHETHER IT’S HIGH OR LOW.

BOUNCING BACK OF WAVES FROM A BARRIER THEY CANNOT PASS THROUGH IS CALLED REFLECTION.

REFRACTION IS THE BENDING OF WAVES AS THEY ENTER A NEW MEDIUM AT AN ANGLE AND CHANGE SPEED.

SOUND IS THE TRANSFER OF ENERGY FROM A VIBRATING OBJECT IN LONGITUDINAL WAVES THAT TRAVEL THROUGH MATTER.

THE MAXIMUM DISTANCE THE PARTICLES OF A MEDIUM MOVE FROM THEIR RESTING POSITIONS WHEN A WAVE PASSES THROUGH IS CALLED THE WAVE AMPLITUDE.

WAVE FREQUENCY IS THE NUMBER OF WAVES THAT PASS A FIXED POINT IN A GIVEN AMOUNT OF TIME.

WAVE SPEED IS HOW FAR A WAVE TRAVELS IN A GIVEN AMOUNT OF TIME; CALCULATED AS WAVELENGTH MULTIPLIED BY WAVE FREQUENCY.

THE DISTANCE BETWEEN TWO CORRESPONDING POINTS OF ADJACENT WAVES, SUCH AS THE DISTANCE BETWEEN TWO ADJACENT CRESTS OF A TRANSVERSE WAVE IS CALLED THE WAVELENGTH

PERCEIVED LOUDNESS OF A SOUND, DETERMINED BY THE AMPLITUDE OF A SOUND WAVE
