Which of the following statements are true? Which one or more? a. The pitch of the voice is affected by the amplitude of vibration of the vocal cords, but not by frequency dependent acoustic resonance. b. D The low frequency range which contains the consonants is more important for understanding speech than the high frequency range from about 1 k Hz to 5 k Hz which contains the vowels. c. The high frequency range from about 1 k Hz to 5 k Hz which contains the consonants is more important for understanding speech than the low frequency range which contains the vowels. d. The pitch of speech sounds is produced by articulation or movement of the tongue, lips, lower jaw and soft palate to modify the airflow.

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
