43. In predicting the motion of tsunamis generated in the sea, and interacting with shoreline objects. A rippletank is used to generate straight waves in region A that travel toward region B, which is separated fromregion A by a straight boundary. The frequency of the generator is 2.5 Hz, and the waves travel in region Awith a speed of 15 inregion B leave the boundary at 50°,(a) use Snell's law to find the relative index of refraction between the two regions (2)(b) find the wavelength in each region (2)

Here is the step-by-step explanation Part a): Use Snell's Law to Find the Relative Index of…

2. Superposition of waves moving in the same direction. Two traveling waves with the equations y₁ = A sin(kx-w₁t) and y₂ = A sin(k₂x - w₂t + p) are present in a medium. (a) Find the equation of the wave function resulting from the superposition of the two waves. (b) Describe the resulting superposition wave. Can it produce stationary waves? (c) If the speed of the waves in the medium is 6 m/s, and each wave has a wavelength of 2 m and 3 m, find the superposed wave function. Draw a wave function at t = 0 s if the phase difference (i) = 0°, (ii) = 90°, and (iii) 4 ) = 180°. (d) As in point (c), but both waves have the same wavelength, say 2 m.
The ionosphere is the ionized part of the upper layer of the earth's atmosphere. The air molecules there are ionized by solar radiation. This layer of the atmosphere is a fairly good conductor, and radio waves are often "bounced" off the bottom of the ionosphere back toward the earth, in a process called skip or skywave propagation. Due to these properties, the space between the surface of the earth and the bottom of the ionosphere acts like a closed wave guide that will exhibit resonance for very low frequencies. Resonance excitations in the cavity are caused by lightning strikes, which hit the earth about 50 to 100 times a second. These low atmospheric resonance frequencies are known as Schumann resonances, named after the physicist Winfried Otto Schumann, who first calculated them in 1952. There are several Schumann frequencies that occur in the low frequency background, which ranges from 3 to 60 Hz. The highest intensity resonance mode (called the fundamental) occurs at 7.83 Hz.…

1) If you want to know the speed of a long-wavelength wave (e.g. tsunami or tide), you can use the shallow-water wave velocity equation v=gd where g is acceleration due to gravity (~10 m/s2), d is water depth (in meters), and v = speed (in meters per second). a) Calculate the speed of a tsunami (in meters per second), assuming an average ocean depth of 4000m. b) Convert the speed of a tsunami from meters per second to meters per hour (note that 1 hr = 3600 seconds). c) Convert the speed of a tsunami from meters per hour to miles per hour (note that 1 mile = 1600m).

Suppose an ocean wave under fairly calm conditions has a height of 1/3 meter and carries a power of 500 watts for every meter along the length of the swell. These are typical values for a calm day at sea. How much more energy would be carried by the waves of a strong gale that are 10 meters high (33 feet!). A hurricane creates even more powerful waves with astounding energy. 27,000 times more energy 900 times more energy the same energy 30 times more energy
