What is the ratio between the energies of two radiations, one with a wavelength of `6000 Å` and the other with `2000 Å [1 Å = 10^(-10)m]`?

Explanation

To find the ratio between the energies of two radiations with given wavelengths, we can use the formula for energy associated with electromagnetic radiation:

\[ E = \frac{hc}{\lambda} \]

Where:
- \( E \) is the energy,
- \( h \) is Planck's constant (\( 6.626 \times 10^{-34} \, \text{Js} \)),
- \( c \) is the speed of light (\( 3 \times 10^8 \, \text{m/s} \)),
