• Q7
What is pitch and what is it determined by?
The highness and lowness of a sound which is determined by the period of a sound wave.
The highness and lowness of a sound which is determined by the frequency of a sound wave.
The loudness of a sound which is determined by the amplitude of a sound wave.
The highness and lowness of a sound which is determined by the amplitude of a sound wave.

• Q8
How does frequency affect pitch?
If the wave's frequency decreases, the pitch also increases.
It does not affect the pitch of the sound.
If the wave's frequency increases, the pitch also decreases.
If the wave's frequency increases, the pitch also increases.

• Q9
What is intensity and its units of measure?
The amount of energy in each wave: measured in hertz (Hz).
The speed of a wave: measured in meter per second (m/s).
The number of waves: measured in decibels (dB).
The amount of energy in each wave: measured in decibels (dB).

• Q13
How does amplitude affect the amount of energy a wave carries?
The larger the amplitude of a wave the less energy it carries.
It does not affect the carried energy.
The shorter the amplitude of a wave the more energy it carries.
The larger the amplitude of a wave the more energy it carries.

• Q14
How does frequency of a wave affect wavelength?
As frequency increases, wavelength stays the same
As frequency increases, wavelength increases, too
As frequency increases, wavelength decreases.
As frequency decreases, wavelength stays the same
