Longer wavelengths, such as those in the infrared or microwave regions, offer several benefits:
Non-Destructive Analysis: These wavelengths are less likely to damage samples, making them suitable for delicate nanomaterials. Deeper Penetration: Longer wavelengths can penetrate deeper into materials, providing information about internal structures that are inaccessible to shorter wavelengths. Lower Cost: Equipment for generating and detecting longer wavelengths is generally less complex and less expensive.
