WAVES/SOUND

HERTZ

• Hertz is the SI unit of waves frequency,where 1 hertz equals 1 wave passing a fixed point per second.

MEDIUM

• Medium is the name for the matter that waves can travel through

PITCH

• The way a person perceived the frequency of a sound,whether it's high or low

FREFLECTION

• Bouncing back of waves from a barrier they cannot pass through is called reflection

REFRACTION

• Bouncing back of waves from a barrier they cannot pass through is called reflection

SOUND

• Sound is the transfer of energy from a vibrating object in longitudinal waves that travel through matter

WAVE FREQUENCY

• Bouncing back of waves from a barrier they cannot pass through is called reflection

WAVES SPEED

• Wave speed is how far a wave travels in a given amount of time; calculated as wavelength multiplied by wave frequency

WAVE LENGTH

• 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

VOLUME

• perceived loudness of a sound, determined by the amplitude of a sound wave
