I am really stuck
[b]1. The wave speed of a longitudinal wave in steel is 5941 m/s. The Speed of a longitudinal wave in water is 1482 m/s. If a bar of steel is struck with a hammer and a wave with wavelength 10.24 m travels through the steel into water, what will be the wavelength of the wave in water...
[b]1. Waves traveling along a string have a wavelength of 2.4 m. When the waves reach the fixed end of the string, they are reflected. How far from the end are the first two antinodes?
[b]2. Not sure what to use
[b]3. I have no really a clue on what to do, if some one could explain...
