Show hintHide hint
Think about how loud the sound is.
Question 2.
What is the unit of frequency?
Show hintHide hint
It starts with an 'H' and is related to vibrations.
3Question 3.
What unit measures frequency?
- Decibels
- Hertz
- Watts
Show hintHide hint
Look for the unit related to cycles per second.
4Question 4.
True or False: Amplitude is directly related to the loudness of sound.
- True
- False
Show hintHide hint
Higher wave heights indicate louder sounds.
Question 5.
Design a sound system that prioritizes sound quality. Discuss how each characteristic of sound waves—amplitude, frequency, wavelength, and speed—plays a role in your design choices.
Show hintHide hint
Consider environments like concert halls or home theaters.
Question 6.
A sound has a frequency of 1000 Hz and travels through air at 343 m/s. Calculate its wavelength. If it were to travel through water at 1482 m/s, what would the new frequency be?
Show hintHide hint
Use the relationships v = f × λ for both air and water.
