To determine which student is correct regarding the relationship between wavelength and frequency, we can refer to the fundamental equation relating these two concepts in physics:
\[ c = \lambda \cdot f \]
Where:
- \( c \) is the speed of light (approximately \( 3.00 \times 10^8 \) m/s in a vacuum),
- \( \lambda \) is the wavelength, and
- \( f \) is the frequency.
From this equation, we can derive the following relationships:
- Wavelength (\( \lambda \)) is inversely proportional to frequency (\( f \)): as the frequency increases, the wavelength decreases, and vice versa.
Thus, the correct statement should reflect that relationship.
To determine who is correct among Franco, Anya, Darius, and Kathryn, we'd need to see their specific statements regarding wavelength and frequency. Please provide their statements so we can identify which student has the correct understanding.
