Write P if only statement A is correct, H if only statement B is correct, Y if both statements are correct and S if both statements are incorrect. 1. A. Waves are created by vibrations. B. As wave moves through a medium, the individual particles of the medium move from the source of the wave to another location some distance away 2. A. Doubling the frequency of a wave source (without altering the medium) doubles the speed of the wave. B. Amplitude and frequency affects the energy of a wave. 3. A. High frequency waves are far apart and low frequency waves are close together. B. X-ray waves are low energy waves. 4. A. You cannot reflect all waves. B. All waves are visible. 5. A. During refraction, a wave bends because it hits the edge of a barrier. B. As a wave changes media, its speed changes.

5. A sound wave is produced in air, with a frequency of 200 Hz. (The speed of sound in air is around 340 m/s)a. What is the wavelength of the sound wave in air?b. If that same wave travelled underwater, its speed would be 1500 m/s. What would its new frequency be? What would its new wavelength be?c. If that same wave travelled through a wall, its speed would be 3400 m/s. What would its new frequency be? What would its new wavelength be?Red light and blue light move through space. Red light has a wavelength of 700 nm; blue light has a wavelength of 400 nm. Questions 6-8 compare the two kinds of light moving through space. (1 nm = 10-9 m)
