A device at the bottom of the sea emits a sound wave of frequency 200 Hz.(i) The speed of sound in sea-water is 1500 m / s.Calculate the wavelength of the sound in sea-water.

The speed of sound is dierent in dierent media. For example, in water it is ~1500 m/s. Draw a model to explain why sound propagates faster in water. Based upon your model, predict whether or not the speed of sound would be faster or slower through a wooden door than water.

A drum is struck, producing a wave with a wavelength of 1.10 meters and a speed of 343 m/s. What is the frequency of the wave? 3. Sonar is a device that uses reflected sound waves to measure underwater depths. If a sonar signal has a frequency of 288 Hz and the speed of sound in water is 1,498 m/s, what is the wavelength of the sonar signal? 4. A dog whistle is designed to produce a sound with a frequency beyond that which can be heard by humans. If a particular whistle produces a sound with a frequency of 2.5x10 4Hz, what is the sound’s wavelength? Assume the speed of sound in air is 343 m/s. Electromagnetic Waves: 5. [Radio waves] A certain FM radio station broadcasts electromagnetic waves at a frequency of 9.05x10 7Hz. These radio waves travel at a speed of 3x10 8m/s. What is the wavelength of these radio waves? 6. [Visible light] A student asks your physics teacher what his favorite color is. Your teacher provides the following straightforward and understandable response: “The wavelength of light that corresponds with my favorite color is 623 nanometers”. Use the speed of light to calculate the frequency that corresponds to this wavelength. 7. Using values from this assignment: How does the speed of sound in air compare to the speed of sound in water? 8. Using values from this assignment: How do the speed of sound and light compare? 1.31 meters .+
