📚 Topic Summary
Sound waves are vibrations that travel through a medium (like air or water). Humans can typically hear sounds between 20 Hz and 20,000 Hz. Frequencies below 20 Hz are called infrasound, and frequencies above 20,000 Hz are called ultrasound. Animals like dogs and bats can hear ultrasound. Understanding these ranges helps us use sound in technologies like medical imaging and sonar.

🧮 Part A: Vocabulary
Match the terms with their correct definitions:

Term

1. Infrasound
    A. Sound waves with frequencies above 20,000 Hz

2. Ultrasound
    B. The number of cycles of a wave per second, measured in Hertz (Hz)

3. Frequency
    C. Sound waves with frequencies below 20 Hz

✍️ Part B: Fill in the Blanks
Complete the following paragraph using the words: Hertz, Ultrasound, Infrasound, 20, 20000.
Humans can typically hear sounds between _____ Hz and _____ Hz. Sounds below this range are called _____, and sounds above this range are called _____. Frequency is measured in _____.

🤔 Part C: Critical Thinking
Why is understanding the frequency ranges of sound waves important in fields like medicine and engineering?
