1. Two boats are anchored 4 m apart. They bob up and down every 3 s, but when one is up, the other is down. There are never any wave crests between the boats. Calculate the velocity of the waves.
2. A standing wave in a clothesline has 4 nodes and 3 antinodes. The clothesline is 12 m long and is vibrating at 0.50 vibrations per second. What is the speed of the wave?
3. A sound wave travels from A to B in the diagram below.
A ------------------------> B
In which directions do the particles of the medium vibrate?
a. up/down
b. left/right
My teacher did not teach us ANY of these concepts, except the ultilization of v=(wavelength)(frequency). I do not know what a node or antinode is, and the other two problems confuse me. Thank you for your help!
