- Which glass treatment process is preferred? A) heat-treatmentB) chemical tempering
- What happens to the frequency and pitch if the sound source is moving away from you?
- On average, what is the highest frequency adolescents and adults can hear? think about our little demo in the classroom when we listened to different frequencies)
- When a sound source moves toward you, what happens to the wave speed? (read this carefully)
- What happens to the frequency and pitch if the sound source is moving toward you?
- What is the speed of sound in air? (what is it in m/s? What is it in mph?)
- If a sound wave has a wavelength of 5m in room temperature air, what is its frequency?
- At what decibel would it be extremely painful to your ears?
- If 2 crests of equal amplitude are traveling towards each other, what will happen when the 2 crests meet?
- A wave has a frequency of 600 Hz and a speed of 20 m/s. What is its wavelength?
- During the Doppler effect, what property of waves is changing?
- What if a crest with double the amplitude meets up with a trough (that has less amplitude. What will be the outcome of the resultant wave when they meet?
- If a crest is traveling in one direction and a trough is traveling toward that crest, what happens when they meet Both the crest and trough have the same amplitude.
