Choose the correct option relating wave lengths of different parts of electromagnetic wave spectrum:

1. A $\lambda$_{radio waves} > $\lambda$_{micro waves} > $\lambda$_visible > $\lambda$_x-rays Correct answer
2. B $\lambda$_visible > $\lambda$_x-rays > $\lambda$_{radio waves} > $\lambda$_{micro waves}
3. C $\lambda$_visible < $\lambda$_{micro waves} < $\lambda$_{radio waves} < $\lambda$_x-rays
4. D $\lambda$_x-rays < $\lambda$_{micro waves} < $\lambda$_{radio waves} < $\lambda$_visible
