(Answered) 1if a wave traveling through air decreases its wavelength

Academics

1. If a wave traveling through air decreases its wavelength by half, describe what happens to the wave speed and frequency.

2. A transverse wave is traveling down a rope with mass, m = 10 kg, and length, L = 50 m. If the rope is under a tension force of 2000 N, calculate the wave speed of the transverse wave. Show your work.

3. If a slinky has a mass of 0.5 kg and 100 loops, calculate the mass density (m/L) of a slinky that is stretched 5 m, but only 80 loops are stretched. Show your work.

4. Cite one example when you have experienced the Doppler effect and explain how it represented this scientific principle.
