    La frequenza di una sinusoide dipende 

    • A.

      Dall’ampiezza della lunghezza d’onda

    • B.

      Dal periodo della sinusoide

    • C.

      Dal numero di cicli in un secondo

    • D.

      Dal numero di cicli in un minuto

    Correct Answer
    C. Dal numero di cicli in un secondo
    Explanation
    The frequency of a sinusoid depends on the number of cycles in one second. This means that the more cycles the sinusoid completes in one second, the higher its frequency will be. The amplitude, wavelength, and period of the sinusoid do not directly affect its frequency.

    Il movimento di un'onda sonora è indicato graficamente da una:

    • A.

      Sinusoide

    • B.

      Co-sinusoide

    • C.

      Onda circolare

    • D.

      Tangente

    Correct Answer
    A. Sinusoide
    Explanation
    The correct answer is sinusoide. A sinusoide is a graphical representation of a sound wave, where the displacement of particles in the medium varies sinusoidally with time. It is characterized by its amplitude, frequency, and wavelength. The other options, co-sinusoide, onda circolare, and tangente, do not accurately represent the graphical representation of a sound wave.

    • C.

      Ampere

    • D.

      Hz

    Correct Answer
    D. Hz
    Explanation
    The correct answer is Hz because Hz is the unit of measurement for frequency. Frequency refers to the number of cycles or oscillations of a wave that occur in one second. It is commonly used to measure the frequency of sound waves, radio waves, and electrical signals. dB is the unit of measurement for sound intensity, Watt is the unit of measurement for power, and Ampere is the unit of measurement for electric current.

    L’altezza del suono dipende:

    • A.

      Dall’ampiezza dell’onda

    • B.

      Dalla forma dell’onda sonora

    • C.

      Numero di cicli al secondo

    • D.

      Dal voltaggio elettrico dell’onda

    Correct Answer
    C. Numero di cicli al secondo
    Explanation
    The correct answer is "numero di cicli al secondo" which translates to "number of cycles per second" in English. This is because the pitch or frequency of a sound is determined by the number of cycles or vibrations that occur in a second. The more cycles there are per second, the higher the pitch of the sound. Therefore, the number of cycles per second is directly related to the height or pitch of the sound.

    L’ampiezza di una sinusoide si misura in

    • A.

      Ampere

    • B.

      Watt

    • C.

      Hz

    • D.

      DB

    Correct Answer
    D. DB
    Explanation
    The correct answer is dB. The amplitude of a sinusoid is a measure of its peak value or maximum displacement from the equilibrium position. dB (decibel) is a unit used to measure the intensity or power level of a sound or signal relative to a reference level. In the context of a sinusoid, dB can be used to quantify the magnitude or strength of the signal. Ampere measures electric current, Watt measures power, and Hz measures frequency, but none of these units directly measure the amplitude of a sinusoid.

    • D.

      La durata

    Correct Answer
    C. L'intensità
    Explanation
    The correct answer is "l'intensità". In Italian, "l'intensità" translates to "the intensity". In the context of a sinusoid, the amplitude refers to the maximum displacement of the waveform from its equilibrium position. This maximum displacement is directly related to the intensity of the sinusoid. Therefore, the correct answer is "l'intensità".

    • D.

      Grave/acuto

    Correct Answer
    D. Grave/acuto
    Explanation
    The correct answer is "grave/acuto" because these terms refer to the pitch or frequency of a sound. "Grave" is used to describe a low-pitched sound, while "acuto" is used to describe a high-pitched sound. This terminology is commonly used in music and sound studies to describe the height or depth of a sound.

    L’ampiezza (intensità) di un suono è indicata con:

    • A.

      Forte/piano

    • B.

      Grave/acuto

    • C.

      Lungo/corto

    • D.

      Veloce/lento

    Correct Answer
    A. Forte/piano
    Explanation
    The correct answer for indicating the loudness (intensity) of a sound is "forte/piano". In music, "forte" means loud and "piano" means soft. These terms are used to describe the dynamic level or volume of a sound. When a sound is played forcefully or with a lot of energy, it is considered "forte". On the other hand, when a sound is played softly or with less energy, it is considered "piano". Therefore, "forte/piano" is the correct answer for indicating the amplitude (intensity) of a sound.
