Asound mixer is impressed by the new equipment that was just installed in his recording studio. he says that now he will be able to singers and musicians produce better cds because he can eliminate unneeded and undesired wavelengths. what term describes the characteristic of sounds waves that the sound mixer is now able to alter?
a. amplitude
b. volleying
c. frequency
d. saturation
e. wavelength

c. frequency  

Explanation:

Frequency refers to the flow at which a vibration develops into a wave. Moreover, frequency is typically measured per second, and it can occur in a material like sound waves or in an electromagnetic field, such as radio waves and light. As a result, the sound mixer can exclude unwanted vibrations that turn into sound waves.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
