What is the vertex form of $y={x}^{2}-4x-3$?

1. The visible spectrum shows that blue has a shorter wavelength than red, which has a longer wavelength.
2. Water molecules absorb longer wavelength light more efficiently than shorter wavelength light.
3. Blue light is having a shorter wavelength, and the absorption of blue color by water will be less.
4. Water will absorb all other light with longer wavelengths.
5. According to Rayleigh criteria, light having a shorter wavelength will scatter more.
6. Blue color absorption by water is lower, and blue color scattering is higher.
7. Therefore, the sea looks blue.
