To find the frequency \( f \) of a wave, you can use the formula:
\[ f = \frac{c}{\lambda} \]
where:
- \( c \) is the speed of light (approximately \( 3 \times 10^8 \) m/s),
- \( \lambda \) is the wavelength in meters.
However, you haven't provided the wavelength \( \lambda \) in your question.
If you provide the wavelength, I can help you calculate the frequency \( f \) and determine which of the options A, B, or C is correct. Please provide the wavelength, and I'll assist you further!
