Answer:
A. 200 Hz
B. Speaker B.
Explanation:
We'll begin by defining the frequency.
The frequency of a wave is defined as the number of vibrations made in 1 second. Mathematically it can be represented as:
Frequency (f) = number of vibration (n) / time (t)
f = n / t
A. Determination of the frequency produced by loud speaker A.
Number of vibrations (n) = 200
Time (t) = 1 s
Frequency (f) =?
f = n / t
f = 200 / 1
f = 200 Hz
B. Determination of the loudspeaker that produces the highest frequency of vibrations.
We shall determine the frequency produced by each speaker. This is illustrated below:
For speaker A:
Number of vibrations (n) = 200
Time (t) = 1 s
Frequency (f) =?
f = n / t
f = 200 / 1
f = 200 Hz
For speaker B:
Number of vibrations (n) = 400
Time (t) = 1 s
Frequency (f) =?
f = n / t
f = 400 / 1
f = 400 Hz
SUMMARY:
Speaker >>>> Frequency
A >>>>>>>>>> 200 Hz
B >>>>>>>>>> 400 Hz
From the above illustration, speaker B produces the highest frequency of vibration.
