If the speed of sound is 343 m/s and her voice is at a frequency of 240 Hz, then how far away is the canyon wall?An electromagnetic wave traveling at 3 × 108?m/s has a 0.89?m wavelength. What is the frequency of this wave?Determine whether the amplitude & wavelength for each wave below is high/big or low/small. When astronauts are outside of a spacecraft on a spacewalk, why do they use headphones and microphones to communicate with each other?Two waves overlap each other such that the combined amplitude is smaller than the amplitude of either wave. This is a good example of:Compare transverse & longitudinal waves.Two waves of the same frequency and wavelength interfere with each other. The first wave has amplitude?A1= 23 cm and wavelength?λ1?= 2 m. The second wave has amplitude?A2?= 30 cm and wavelength?λ2?= 2 m. What is the amplitude of the sum of the two waves if the waves are 180° out of phase?A sound wave has a frequency of 540 Hz. What is the period of this wave?Two waves of the same frequency and wavelength interfere with each other. The first wave has amplitude?A1= 49 cm and wavelength?λ1?= 4 m. The second wave has amplitude?A2?= 55 cm and wavelength?λ2?= 4 m. What is the amplitude of the sum of the two waves if the waves are exactly in phase?What characteristics are associated with?high energy?for a wave?Two scientists set up an experiment to measure the speed of sound through a metal. If they measured the frequency of the sound to be 800?Hz and the wavelength to be 3?m, what is the speed of sound in the metal?The frequency spectrum of a certain wave shows a single peak at 430 Hz. What would be the period of the wave as shown on its waveform?A sound wave moving through a medium different from air has a wavelength of 1.9 m and a speed of 250 m/s. What is the frequency of the sound wave?A hiker in a large canyon calls out the word “Hi” and hears the echo 3?s later. How far away from the canyon wall is he? (Assume that the speed of sound in air is 340?m/s.)What is the wavelength of a sound waves traveling at 343 m/s with a period of 0.049 s?Rank the following from smallest wavelength to biggest wavelength. When a bell is rung by striking it with a metal rod, what direction do the sound waves produced by the bell move?An ocean buoy moves up-and-down once every 5 seconds due to passing water waves. What is the wavelength of the waves if their speed is 6 m/s?What could you do to a wave to increase its energy?What is the wavelength of the wave in the graph?Two sound waves combine to create a louder sound than either of them individually. What is this a good example of?For the 2 waves below, draw a wave that is 180o out of phase.
