Waves O 1.2 Wave Properties

Wave Properties Amplitude – distance from the null point to the crest or the trough The larger the amplitude, the greater the energy. The smaller the amplitude, the smaller the energy. Wavelength-the distance from one point on a wave to the identical point on the next wave

Waves

Waves Frequency – the number of waves that pass after a second. Period-time it takes to have one wave pass Number of waves per a second is measured in Hz. High pitch sounds have high frequencies. Low pitch sounds have low frequencies.

Waves

Waves Wavelength determines color. Red-large wavelength Blue-short wavelength Wave speed – the speed at which a wave travels Frequency x wavelength = wave speed
