Q4. Frequency usually stays the same when sound moves from one medium to another. If a sound wave is 0.785 m long when travelling in 22.0 'C in air, then determine the length of the wave after it travels into marble. Use the information in the table of your notes. Q5. During summer storms it is common to see flashes of lightning followed by the thunder a few seconds later. Given an air temperature of 35 .C, develop a rule that determines whether a lightning strike occurred within 1.00 km. That is, how many seconds would there be between seeing lightning and hearing thunder if the lightning strike were 1.00 km away? @ Mrs. Brosseau's BinWave Interference Practice Date: Name: Q1. Draw the wave interference of the two pulses as they pass through each other. Each pulse moves one square per second. t = 0s t = 1s t = 2s t = 3s Describe how the pulses interfere with one another. @Mrs. Brosseau's BindeQ2. Draw the wave interference of the two pulses as they pass through each other. Each pulse moves one square per second. t = 0s t = 1s t = 2s t = 3s t = 4sNAN Q3. Draw the wave interference of the two pulses as they pass through each other. Each pulse moves one square per second. t = 0s t = 1s t = 2s t = 3s t = 4she now the wave interference of the two pulses as they pass through each other. - allare per second. TTTTTT Q4. Draw the resultant wave by adding the individual amplitudes. Start with key points along the wave. Mrs. Brosseau's BinderTVn. The Speed of Sound Date: Practice Name: Q1. Explain, in words a young child would understand, why sound generally travels faster through solids than gases. Q2. Calculate the speed of sound in air at the following temperatures. Temperature Speed of Sound 30.0 .C 15.0 .C 0.00 .C -5.00 .C Q3. Calculate the air temperature given the speed of sound Speed of Sound Temperature 362 m/s 333 m/s 328 m/s 303 m/s @ Mrs. Brosseau's Binder
