Show hintHide hint
Think about how a mirror reflects light.
Question 2.
Define the reflection coefficient.
Show hintHide hint
Look for terms like 'ratio' or 'proportion'.
3Question 3.
What happens to the wave when it reflects off a fixed end?
- Inverts
- Keeps Same Phase
- Amplifies
Show hintHide hint
Think about how a wave behaves in a mirror.
4Question 4.

- True
- False
Show hintHide hint
Consider energy conservation in wave interactions.
Question 5.
A wave encounters a boundary where Z1 = 50 and Z2 = 100. If the incident wave has an amplitude of 10 units, what are the amplitudes of the reflected and transmitted waves?
Show hintHide hint
Use the formulas for calculating reflections.
Question 6.
