- An observer hears a sound from a vehicle that is parked. Then, the vehicle starts moving toward her. What will happen to the frequency and wavelength of the waves when the vehicle starts moving toward her? Your answer: The frequency and wavelength will both increase. The frequency and wavelength will both decrease. The frequency will increase and the wavelength will decrease. The frequency will decrease and the wavelength will increase.ultrasound physics What wave property is changed by an increase in intensity? Wavelength Frequency Acoustic velocity Acoustic pressure.Negative decibels? Our discussion of decibels did not mention that they can be negative. On the Redmond, Washington campus of Microsoft is an anechoic chamber that, according to Guinness World Records, is the quietest place in the world. It measures –20.3 decibels. a. What is the relative intensity of a sound measuring –1 decibels? Round your answer to one decimal place. b. What is the relative intensity of a sound measuring –10 decibels? Round your answer to one decimal place. c. What is the relative intensity of Microsoft's anechoic chamber? Round your answer to three decimal places. d. Is it possible for the relative intensity to actually be zero?
- q2A man he uses a call with a power of 200 Watts to signal to two people that he is under distress. Assuming the call emanates from the man as a point source, what would the intensity of the sound be to the one person who is 100 m away? b.) By what factor does the intensity of the sound decrease when it reaches the second person 500 m away? c.) If the call has an frequency of 4,000 Hz and the speed of sound is 344 m/s, then what is the wavelength of the sound waves produced?A sound pulse emitted underwater reflects off a school of fish and is detected at the same place 0.04 s later (see the figure below). How far away are the fish? (Assume the water temperature is 20°C.) m
