Draw schematics of the configurations shown but replace the molecular bonds with springs: each bond has a spring constant (kn) and each molecule has a mass (mn). Describe how you might develop a model for calculating the resonant frequency for each of the three molecular configurations (you don’t have to work out the math!). This model describes “acoustic phonons”.

Jeremiah was investigating different aspects of sound waves. He listened to two sounds. Sound 1 had a lower pitch than Sound 2. Based on this information, how was Sound Wave 1 different from Sound Wave 2? O A. Sound Wave 1 had a smaller amplitude than Sound Wave 2. B. Sound Wave 1 had a shorter wavelength than Sound Wave 2. C. Sound Wave 1 had a slower speed than Sound Wave 2. D. Sound Wave 1 had a lower frequency than Sound Wave 2.

ound wave in air. b) In water the speed of sound is different. The speed of a sound wave in water is 1300 m/s. The sound wave has a frequency of 1000HZ. Calculate the wavelength of this sound wave.

L 1.1.4 Quz: Wave Interactions Questlon 4 of 10 A sound wave traveling through dry air has a frequency of 16 Hz, a wavelength of 22 m, and a speed of 350 m/s. When the sound wave passes through a cloud of methane, its wavelength changes to 28 m, while its frequency remains the same. What is its new speed?

How is white light different from the rest of the electromagnetic spectrum? White light is capable of altering its wavelength. O White light can travel through empty space and matter. White light is invisible to the human eye. O White light has a spectrum of visible colors.

The figure shows the circular wave fronts emitted by two sources, the wavelength for both idential waves is 1.4 m. What is the path-length difference at point Q, in meters? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
