Waves The highest point of a transverse wave The area in a longitudinal wave where the particles are close together The ability to move or change an object, or what a wave carries Type of mechanical wave in which energy runs at right angles to the wave Type of mechanical wave in which energy flows parallel to the wave The lowest point of a transverse wave Area in a longitudinal wave in which the particles are spread out The material through which a mechanical wave travels Describe the motion of particles in the medium for each type of wave. How does this motion compare to the direction the wave travels? a. Transverse wave b. Longitudinal wave What is the difference between mechanical waves and electromagnetic waves? What is the equation for the speed of a wave? Calculate the wave speed of a wave that has a frequency of 5 Hz and a wavelength of 10 m. What are the two types of interference? Which results in a large amplitude? Which results in a smaller amplitude?Identify the number of nodes and antinodes for each of the following: Sound What determines the pitch of a musical note? What happens to pitch when the frequency of sound waves increases? What happens to the frequency of a sound wave if the wavelength decreases? Which sound wave will have a greater amplitude, a wave with many compressions or a wave with few compressions? What is the effect of greater amplitude of a sound wave? What type of wave is a sound wave - longitudinal or transverse? What causes a change to the speed of sound? a. frequency c. wavelength b. wind conditions d. loudness e. air temperature a. low pitched b. high pitched When an automobile moves towards a listener, the sound of its horn seems relatively c. normal
