Which is the correct ascending order of wavelength?
(a) \( \lambda_{\text {visible }}\lambda_{X \text {-ray }}\lambda_{\text {gamma-ray }}\lambda_{\text {microwave }} \)
(b) \( \lambda_{\text {gamma-ray }}\lambda_{X \text {-ray }}\lambda_{\text {visible }}\lambda_{\text {microwave }} \)
(c) \( \lambda_{X \text {-ray }}\lambda_{\text {gamma-ray }}\lambda_{\text {visible }}\lambda_{\text {microwave }} \)
(d) \( \lambda_{\text {microwave }}\lambda_{\text {visible }}\lambda_{\text {gamma ray }}\lambda_{X \text {-ray }} \)
