Sound Waves Practice Problems Name___________________________________ PSI AP Physics 1 Multiple Choice Two sound sources S1 and S2 produce waves with frequencies 500 Hz and 250 Hz. When we compare the speed of wave 1 to the speed of wave 2 the result is: Twice as great (B) One-half as great (C) The same (D) It cannot be determined with the given information. Which of the following is a true statement about the speed of sound in three different materials: air, water, and steel? Vair > Vwater > Vsteel Vair > Vwater = Vsteel Vair < Vwater > Vsteel Vair < Vwater < Vsteel Use the following picture for questions 3 and 4. A sound source S radiates a sound wave in all directions. The relationship between the distances is SA = AB = BC = CD. Which of the following points oscillates at the highest frequency? A (B) Point B (C) Point D (D) All points have the same frequency A source S radiates a sound wave in all directions. The relationship between the distances is SA = AB = BC = CD. Which of the following points oscillates with the greatest intensity? A (B) Point B (C) Point D (D) All points have the same intensity The loudness of a sound wave increases with increasing which of the following: (A) Frequency (B) Amplitude (C) Wavelength (D) Speed of sound A wave travels from air into water. Which of the following doesn’t change? (A) Frequency (B) Amplitude (C) Wavelength (D) of sound A sound wave resonates in a tube with two open ends.
