An isotropic point source of sound S emits sound waves with a wavelength of 0.85 m. Beam 1 is directed directly to detector D at a distance of L = 10 m.Beam 2 arrives at the detector after bouncing off the surface as shown in the figure. The reflection causes the phase shift of the wave by 0.5λ.Determine the smallest (non-zero) distance d so that both waves arrive at the detector(a) with opposite phase,(b) with the same phase.
The bending or spreading out of a wave at an obstacle or at the edges of an opening is called diffraction. (Sin 0=1/d) The amount of diffraction, (for all wave types) depends on the wave's wavelength A and the relative size of the opening d. If the speed of sound is 343 m/s and the speed of light is 3x10^8 m/s. What would be the ratio of the size of an opening to give the same amount of diffraction for sound and light? Take the frequency of sound at 500 Hz and light at 5x10^14 Hz ratio (Alight /Asound = dight /dsound) Over a million times smaller а. b. Over a thousand times smaller C.

A bat emits a sound whose frequency is 81.8 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 41.8 oC, so the speed of sound is not 343 m/s. Assume that air behaves like an ideal gas, and find the wavelength of the sound.
Two identical traveling waves of the form Acos(kx - ωt+ø) are moving in the same direction and are out of phase by ø=π/2 radians. If the amplitude of each wave is 10 cm what is is the amplitude of the superposition of the two waves. Use the trig identity Acos(x) + Acos(y) = 2Acos(x+y)/2)cos((x-y)/2). Substitute x = kx - ωt and y = kx - ωt + ø and you get 2Acos(ø/2)cos(kx - ωt + ø/2). The amplitude of the superposition wave is 2Acos(ø/2). Plug in ø=π/2 radians and the amplitude of the traveling waves to get your answer. Make sure your calculator is set to radians.

A capillary wave is a wave traveling across the surface of a fluid that is driven by the surface tension within the fluid. The speed v of a capillary wave depends on the density of the fluid ?ρ , the wavelength of the wave ?λ, and the surface tension ?σ . The SI units of surface tension are J/m2. The capillary wave speed can be written as ?=???????v=kσaρbλc , where k is some unitless constant. What must be the value of c?
