1. A wave train is traveling along a string. Seven waves pass by a point in 3.75 s. The

distance from the top of a crest to the bottom of an adjacent trough is 0.462 cm. Find:

a) the speed of the waves.

b) the tension in the string if it has a length of 1.68 m and a mass of 3.86 g.

2. Suppose that the string in problem #1 is attached to a second string whose linear

density is 0.00552 kg/m. The waves, therefore, travel through the first string and then

through the second. What is their wavelength in the second string if the tension in

both strings is the same?
