The apparent change in frequency or wavelength of a wave observed by a receiver in relative motion to the wave source is known as:
A. Tyndall Effect
B. Raman Effect
C. Doppler Effect✓ Correct Answer
D. Zeeman Effect
💡 Solution & Explanation
The Doppler Effect describes the apparent change in the frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. Phenomenon like the Tyndall effect involves light scattering by colloidal particles rather than relative motion shifts in wave frequency. This principle finds critical applications in astronomy, radar technology, and medical ultrasonography.
