Reflection contrast spectrum

Web5. sep 2013 · The white light contrast spectroscopy has been used for identification of layer numbers of atomically thin material such as graphene 24 and TMDs 25 through … Web7. nov 2024 · Light waves interact with materials by being reflected, absorbed, or transmitted. Reflection occurs when a wave bounces off of a material. For example, a red piece of cloth may reflect red light to our eyes while absorbing other colors of light. Absorbance occurs when a material captures the energy of a light wave.
