The wavelength of a red light with frequency $430 \times 10^{12}\ \text{Hz}$ is $700 \times 10^{-9}\ \text{m}$. What could be true for blue light?
- Aa frequency of $190 \times 10^{12}\ \text{Hz}$ and a wavelength of $450 \times 10^{-9}\ \text{m}$
- Ba frequency of $190 \times 10^{12}\ \text{Hz}$ and a wavelength of $950 \times 10^{-9}\ \text{m}$
- Ca frequency of $670 \times 10^{12}\ \text{Hz}$ and a wavelength of $450 \times 10^{-9}\ \text{m}$
- Da frequency of $670 \times 10^{12}\ \text{Hz}$ and a wavelength of $950 \times 10^{-9}\ \text{m}$
