1 Transmission of Pulses
(Reflection & Refraction)

6 Reflection & Transmission of Pulses
When a pulse travels onto a different medium, there are reflection AND transmission (refraction). The reflected pulse will be inverted if the boundary is a fixed point. The transmitted pulse will travel at a different speed. The frequency is NOT CHANGED.

7 NCEA 2010 Janet and Sophie tie two different ropes together. The ropes are of different thickness. Janet sends a pulse along the rope towards Sophie. The speed of the pulse in the first rope is 4.5 ms–1 and its wavelength is 12.4 cm. The wavelength of the pulse as it travels through the second rope is 8.6 cm. Calculate the speed of the pulse in the second rope.
