Verified answer
6.C-longitudinal
explanation: longitudinal wave
longitudinal waveA longitudinal wave consists of a repeating pattern of compressions and rarefactions.
7.B-Frequency
explanation:The number of cycles of a periodic wave per unit time is called the wave's frequency.
8.A-Crest
explanation:Crest : The highest point of the wave
9.C-Pitch
explanation:Pitch is the highness or lowness of sound.
10.D-Timbre
explanation: Sound "quality" or "timbre" describes those characteristics of sound which allow the ear to distinguish sounds which have the same pitch and loudness. ...
11.B-Longitudinal
explanation: Oscillations where particles are displaced parallel to the wave direction
12.C- Compression
explanation:Places where particles of the medium crowd closer together are called compressions.
13.B-Pitch is inversely proportional to intensity
explanation: Doubling the frequency of pitch forms an octave" Is true about pitch.
14.Transverse Waves
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation.
15.Decibel meter.”« An instrument used to measure the loudness of sounds.
