Wave interactions with boundaries, media, and observers produce distinct observable phenomena. Match each wave phenomenon on the left with its corresponding physical scenario on the right.
- RefractionA straight pencil submerged in a glass beaker appears broken or displaced at the water surface boundary.
- DiffractionA person hears spoken words from around a sharp hallway corner before the speaker comes into direct line of sight.
- Doppler EffectA siren's pitch increases in frequency as an emergency vehicle moves rapidly toward a stationary listener.
- Total Internal ReflectionLight signals propagate long distances through glass fiber cores without leaking through the cladding layer.
Cevap
Refraction correctly matches the submerged pencil appearing broken at the water boundary; Diffraction correctly matches hearing sound around a hallway corner; Doppler Effect correctly matches the siren pitch increasing during vehicle approach; Total Internal Reflection correctly matches light signal confinement in optical fibers.
Each wave phenomenon matches its exact governing physical principle: Refraction is the bending of light due to speed variation across media; Diffraction is wave spreading around physical obstacles; Doppler Effect is the frequency shift due to relative source motion; Total Internal Reflection is complete optical confinement based on critical angle reflection.
