Identify the given values: wavelength \( \lambda = 600 \text{ nm} \) and speed of light \( c = 3.00 \times 10^{8} \text{ m/s} \).
Convert the wavelength from nanometers to meters because the speed of light is in meters per second. Use the conversion \( 1 \text{ nm} = 1 \times 10^{-9} \text{ m} \), so \( \lambda = 600 \times 10^{-9} \text{ m} \).
Recall the relationship between the speed of light, wavelength, and frequency: \[ c = \lambda \times f \] where \( f \) is the frequency.
Rearrange the formula to solve for frequency \( f \): \[ f = \frac{c}{\lambda} \].
Substitute the known values into the equation and calculate the frequency: \[ f = \frac{3.00 \times 10^{8} \text{ m/s}}{600 \times 10^{-9} \text{ m}} \].
