One difference between the light waves coming from a light bulb and water waves on a pond is that (A) light waves occur in three dimensions while water waves occur in two dimensions. (B) light waves can show interference effects, while water waves cannot. (C) light waves all have the same wavelength, while different water waves can have different wavelengths. (D) different light waves have different speeds, while all water waves must have the same speed. (E) all of the above.
2. a. A guitarist strums a guitar string that is 95 cm in length. If the fundamental frequency heard is 200 Hz, what is the speed of a wave through the guitar string? (Fundamental: L=0.5 wavelength). b. What is the wavelength and frequency of the first four overtones for this guitar string? (Overtones: L=(n+1)*0.5 wavelength, where n is the numbered overtone) c. If the speed of sound in the air is given by: Vw = (331 m/s) 1 T 273 K and the temperature is 20 Celsius, how long after she plays the string will an audience member 18 meters away hear the fundamental frequency?
