which one of the following frequencies of a wave in the air can be heard as an audible sound by the human ear? A.0.10Hz B 10 Hz C. 1,000 Hz D. 100,000Hz
C, 1000 Hz. It's about two octaves above middle C
1,000Hz
To determine which frequency of a wave in the air can be heard as an audible sound by the human ear, we need to consider the range of human hearing.
The human ear generally perceives frequencies between 20 Hz (lower limit) and 20,000 Hz (upper limit). Anything below or above this range is usually not audible to us.
Now, let's analyze the given frequencies:
A. 0.10 Hz: This frequency is below the lower limit of human hearing (20 Hz), so it is not audible to us.
B. 10 Hz: Similarly, this frequency is still below the lower limit of human hearing (20 Hz), so it is not audible.
C. 1,000 Hz: This frequency falls within the audible range of human hearing (20 Hz to 20,000 Hz). Therefore, it can be heard as an audible sound by the human ear.
D. 100,000 Hz: This frequency is significantly higher than the upper limit of human hearing (20,000 Hz), so it is not audible to us.
In conclusion, the frequency of 1,000 Hz (C) can be heard as an audible sound by the human ear.
