Question

answer numbers 3,4,5 with correct answer

1. If the handle of a vibrating tuning fork is held against a table, the sound of the tuning fork beams louder. Why?
O 1. the tuning fork vibrates more when held against the table
2. there is no difference whether the tuning fork is held against the table or not
3. sound from the tuning fork travels faster on the table than in air
4. the vibrating tuning fork causes the table to vibrate, which in turn causes more air to vibrate
2. Which of the following tells the relation between wavelength and period of a wave?
1. the longer the wavelength, the lower the period
2. wavelength and frequency are completely independent of each other
3. impossible to determine
4. the longer the wavelength, the higher the period

pipes?
1. decreases
2. stays the same
3. impossible to determine
4. increases

4. If a huge explosion occurs from a distance, which will you be able to observe first, the sound of the explosion or the tremor of the ground?
1. explosion
2. tremor
3. impossible to determine which will be observed first
4. both will be observed at the same time
5. Suppose you're on a hot air balloon ride, carrying a buzzer that emits a sound of frequency f. If you accidentally drop the buzzer over the side while the
balloon is rising at constant speed, what can you conclude about the sound you hear as the buzzer falls toward the ground?
1. the frequency and intensity increase.
2. the frequency decreases and the intensity decreases.
3. the frequency decreases and the intensity increases.
4. the frequency remains the same, but the intensity decreases.
