A 450 Hz sound wave in 20∘C air propagates into the water of a swimming pool. Assume that the wave's speed in the water is 1480 m/s. What is the wave's frequency in the water? What is the wave's wavelength in the water?

Waves on a particular string travel with a velocity of 35.0 m/s . Successive peaks (maximum points on the wave) are 0.37 m apart along the string . What is the frequency of the wave, in Hz?

A tranverse wave in a medium wave is described by the following equation: y(x,t) = (12 m)cos(3.0x - 120t). What is the speed of this wave? (x and y describe real space with units of meters, and t is time in seconds.)   a. 30 m/s   b. 50 m/s   c. 60 m/s   d. 70 m/s   e. 40 m/s

Transverse waves on a string have wave speed of 8.00 m/s, amplitude of 0.0700 m, and wavelength of 0.320 m. The waves travel in the _x-direction, and at t = 0 the x = 0 end of the string has its maximum upward displacement. Find the Find the transverse displacement of a particle at x = 0.360 m at time t = 0.150 s. 4.95 cm O 9.45cm O 5.49cm O 4.16cm
