Question 1 (2 points) Imagine the image below represent the surface of a pond: r V L A Describe the motion of a water beetle on the surface of the water when it is located along a nodal line. The diagram below shows two waves moving towards each other. For each of the following combinations, determine whether the interference will be constructive, destructive, or intermediate. For example, when point A1 meets point CZ, the wave will destructively interfere, producing no amplitude. A1 A2 wave 1 wave 2 Question 2 (1 point) 31 and C2: Question 3 (1 point) A1 and 82: O Constructive Interference O Destructive Intereference 0 Intermediate Interference Question 4 (1 point) C1 and A2: 0 Constructive Interference O Destructive Intereference 0 Intermediate Interference Question 5 (1 point) B1 and A2: Constructive Interference Destructive Intereference Intermediate Interference Question 6 (1 point) True or False. Constructive interference occurs when AL is a whole number True FalseQuestion 7 (1 point) 3L True or False. Destructive interference occurs when 1' is one half of a whole number. Question 1 (2 points) A fire engine is being driven away from you at a speed of 15.4 m/s. One of the notes in its siren sequence has a fundamental frequency of 244 Hz. If the speed of sound is 338 m/s, the fundamental frequency of that particular note will seem to you to be _Hz. (Give your answer with the correct number of sig digs and do not include units) Question 2 (2 points) An automobile is approaching you at a speed of 50.0 km/h and sounding its horn. The fundamental frequency of the horn sounds to you like 266 Hz. If the speed of sound is 335 m/s, the real fundamental frequency of the horn is _Hz. (Give your answer with the correct number of sig digs and do not include units) A/ Question 3 (2 points) An automobile is approaching you at a speed of 90.0 km/h and sounding its horn. The fundamental frequency of the horn sounds to you like 268 Hz. If the real fundamental frequency of the horn is 248 Hz, the speed of sound is _m/s. (Give your answer with the correct number of sig digs and do not include units. A/
