Concept

# Problem: A wave on a string propagates down a 150 g, 4 cm long string with a 10 cm wavelength before encountering a transition to a new string. If the new string is 250 g in mass and 8 cm long, and both strings have a tension of 100 N, (a) What is the wavelength of the wave that reflects off the transition point between the two strings? (b) What is the wavelength of the wave that passes through the transition point between the two strings?

###### Problem Details

A wave on a string propagates down a 150 g, 4 cm long string with a 10 cm wavelength before encountering a transition to a new string. If the new string is 250 g in mass and 8 cm long, and both strings have a tension of 100 N,

(a) What is the wavelength of the wave that reflects off the transition point between the two strings?

(b) What is the wavelength of the wave that passes through the transition point between the two strings?
