Part 1: Properties of Waves 1. Sketch each of the following waves that are on a spring resting horizontally attached to a wall at one end: a. A pulse wave that is longitudinal b. A periodic wave that is longitudinal c. A pulse wave that is transverse d. A periodic wave that is transverse Part 2: Wave Speed 2. A piano string tuned to middle C vibrates with a frequency of 262 Hz. Assuming the speed of sound in air is 343 m/s, find the wavelength of the sound waves produced by the string. 3. The speed of all electromagnetic waves in empty space is 3.00 x 108 m/s. Calculate the wavelength of electromagnetic waves emitted at the following frequencies (1 MHz = 106 Hz): a. Radio waves at 88.0 MHz b. Visible light at 6.0x108 MHz c. Xrays at 3.0x1012 MHz 4. A sound wave produced by a clock chime is heard 515 m away 1.50 s later. . What is the speed of sound in the air? b. The sound wave has a frequency of 436 Hz. What is the period of the wave? c. What is the wavelength
