1.2 Reflection of Waves

Reflection of wave refers to the return of all or part of the waves when they encounter an obstacle

Characteristics of reflected waves:
1. Frequency - same (because same source)
2. Speed - same (because same medium)
3. Wavelength - same (because frequency and speed are constant)

So, what is changed???

Only direction change
