Question 27 (1 point) Listen Small, high pitched tuning forks that vibrate faster have a higher than larger, low pitched tuning forks. O wavelength O amplitude O frequency O diffraction Question 28 (1 point) Saved Listen Resonance is most closely related to which basic wave interaction? O interference O refraction O diffraction O reflection O Resonance is its own basic wave interaction.Question 29 (1 point) Listen Two students are experimenting with a long slinky as shown in the diagram below. If the students shake their slinky so that the frequency of the waves they generate increases, what will happen to the wavelength of the slinky? The wavelength will decrease O The wavelength will stay the same O The wavelength is unrelated to the frequency The wavelength will increase O Question 30 (1 point) Listen As a car, honking its horn, passes you and moves away from you, the frequency (pitch) that the horn is actually making O decreases increases O stays the same Onone of the aboveQuestion 31 (1 point) Listen A police car's siren has a certain pitch. In which of these cases will the pitch of the sound observed to be higher? O the car and observer are stationary O the car is moving away from the observer O the car is moving towards the observer O the observer is moving away from the car Question 32 (1 point) Listen Which type of interference is being demonstrated at points G, J, M, and N as shown in the diagram below? Amplitude (m) total destructive interference O constructive interference destructive interferenceQuestion 33 (1 point) Listen Two scientists set up an investigation in which a radio transmitter and a sound source (alarm clock) are both placed inside a sealed container, like in the bell jar image below The scientists then pump all of the air out of the container creating a vacuum. Attribution: Image from: https:/fineartamerica.com/featured/alarm-clock-inside-a-bell-jar-science-photo-library.html The scientists then notice that the radio waves can still be detected outside of the container but the sound waves cannot be detected outside of the container. Which of the following explanations fit the results of their investigation? Radio waves are mechanical but sound waves are electromagnetic because radio waves cannot travel through air but sound waves can travel through air. Radio waves are electromagnetic but sound waves are mechanical because the radio waves could travel without a medium but the sound waves could not. Radio waves are mechanical and sound waves are electromagnetic because the radio waves could travel without a medium but the radio waves could not. Radio waves are electromagnetic but sound waves are mechanical because radio waves cannot travel through air but sound waves can travel through air
