What happens to sound waves from an object as it moves toward you?
A). The pitch gets higher because of an increase in wavelength.
B). The pitch gets lower because of an increase in wavelength.
C). The pitch gets lower because of an increase in frequency.
B). The pitch gets higher because of an increase in frequency.
D). The pitch gets higher because of a decrease in wavelength.
Are you sure? I just wanna make sure, is all.
I apologize for the confusion. You are correct. The pitch of the sound waves from an object as it moves towards you will get higher because of a decrease in wavelength.
The correct answer is B) The pitch gets higher because of an increase in frequency.
When an object moves toward you, the sound waves it produces are compressed or "squeezed together." This compression causes the frequency of the sound waves to increase, resulting in a higher pitch.
To understand this, let's consider the definition of frequency. Frequency is the number of cycles or vibrations of a wave that occur per unit of time. In the case of sound waves, frequency determines the pitch of the sound. Higher frequency waves have a higher pitch, and lower frequency waves have a lower pitch.
As the object moves toward you, each individual sound wave it emits gets closer to the next wave, causing the cycles to occur more frequently (i.e., higher frequency). This increase in frequency results in a higher pitch because your ears perceive the sound waves as more rapid vibrations.
To summarize, when an object moves toward you, the pitch of the sound it produces gets higher because of an increase in frequency.
