Monday, December 5th Entry Task Describe how particles move as energy is transferred through a sound wave Schedule: 16.2 Frequency and Pitch Objective: I will explain how frequency and pitch are related. Homework Input and output page complete Please have on desk: ISN, entry task brochure

16.2 Notes Pitch depends on frequency of a sound wave. The characteristic of highness or lowness of a sound is called pitch

16.2 Notes A low pitch would have a low frequency and a long wavelength. A high pitch would have a high frequency and a short wavelength.

16.2 Notes Frequency is measured in waves per second. The unit for frequency is Hertz(Hz).

16.2 Notes Sound waves with a frequency of below 20 Hz are called infrasound and can’t be heard by humans. Elephants use infrasound to communicate over long distances, sometimes up to 20 miles away.

16.2 Notes Sound waves with a frequency of above 20,000 Hz are called ultrasound and can’t be heard by humans. Dolphins and bats use ultrasound to find prey in dark environments.

In your journal Draw a sound wave with a Low Pitch Draw a sound wave with a High Pitch Use the words Pitch, Wavelength and Frequency to explain your drawings

Kids Be Gone 3-4 Sentence summary of article then answer questions below. Why can teens hear the Mosquito device, but adults can’t? Include detail about the human ear. Draw and label an example of a high frequency sound wave. Explain why it is high frequency. Is this sound going to damage the ears of kids who hear it? Explain why or why not. Do you think its fair to use high frequency sounds as a deterrent against kids?

Kids Be Gone Kids have more hair cells in the cochlea so they can pick up a wider range of sound. High Frequency sounds do not damage hearing, but loud sounds do. Do you think its fair to use high frequency sounds as a deterrent against kids?
