Answer: The correct answer is "the frequency has increased".

Explanation:

Frequency is the number of  vibrations in one second. Pitch depends on the frequency. High frequency produces high pitched note. Low frequency produces low pitched note.

In the given problem, a singer raises his pitch one octave. Here, the quality of the sound wave will change. On raising the pitch the frequency will increase.

Therefore, the correct option is " the frequency has increased".

If there is a net force on an object in the direction it is already moving, what has to happen to the speed of the object?
baherus [9]
Net force is an unbalanced force, so the object will change speed or direction.
Either the object may speed up or slow down.
