Which is the correct ascending order of wavelengths?

$\displaystyle \lambda_{\text {visible }}<\lambda_{X-\text { ray }}<\lambda_{\text {gamma-ray }}<\lambda_{\text {microwave }}$

$\displaystyle \lambda_{\text {gamma-ray }}<\lambda_{X-\text { ray }}<\lambda_{\text {visible }}<\lambda_{\text {microwave }}$

$\displaystyle \lambda_{X-\text { ray }}<\lambda_{\text {gamma-ray }}<\lambda_{\text {visible }}<\lambda_{\text {microwave }}$

$\displaystyle \lambda_{\text {microwave }}<\lambda_{\text {visible }}<\lambda_{\text {gamma-ray }}<\lambda_{X-\text { ray }}$
