Final answer:
Humans can hear sounds ranging from 20 Hz to 20,000 Hz. Frequencies of 100 Hz, 1,000 Hz, and 10,000 Hz are audible, while 100,000 Hz is not. Hence, option (a), (b) and (c) are correct.
Step-by-step explanation:
The human ear can detect a wide range of frequencies, specifically from 20 Hertz (Hz) to 20,000 Hz. Sounds with frequencies below this range are considered infrasound and those above are known as ultrasound, neither of which is perceivable by the human ear.
While infrasound and ultrasound are beyond human perception, their applications in various fields highlight their significance, from detecting seismic activity to advanced medical diagnostics, showcasing the diverse utility of sound across different frequency ranges.
Therefore, among the frequencies mentioned in the question, 100 Hz, 1,000 Hz, and 10,000 Hz are within the audible range for humans, while 100,000 Hz is beyond the upper limit of human hearing ability and is categorized as ultrasound. Therefore, the correct answers are options (a), (b) and (c).
