A
2.44 \(\times\) 10^{16} s^{-1}
B
3.69 \(\times\) 10^{16} s^{-1}
C
2.44 \(\times\) 10^{14} s^{-1}
D
3.69 \(\times\) 10^{14} s^{-1}
Verified step by step guidance1
Identify the given quantities: wavelength \(\lambda = 1.23 \times 10^{-6}\) cm and speed of light \(c = 3.00 \times 10^{10}\) cm/s.
Recall the relationship between the speed of light, wavelength, and frequency: \(c = \lambda \times \nu\), where \(\nu\) is the frequency.
Rearrange the formula to solve for frequency: \(\nu = \frac{c}{\lambda}\).
Substitute the given values into the equation: \(\nu = \frac{3.00 \times 10^{10} \text{ cm/s}}{1.23 \times 10^{-6} \text{ cm}}\).
Perform the division to find the frequency in s\(^{-1}\) (Hz).
