(1) Different types of electromagnetic radiation such as radio waves, microwaves, visible light, and x-rays are associated with specific wavelengths. A spectrophotometer is an instrument that performs ...

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. An object appears to be black if it absorbs all the wavelengths of visible light. For example ...

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...

Using this method, IISC team were able to up-convert infrared light of wavelength around 1550nm to 622nm visible light. “This process is coherent – the properties of the input beam are ...

The team has developed an innovative technology that maximizes near-infrared light capture performance ... light capture ...

They're your eyes, and they receive signals that fall in the range of visible light. Light, heat, radio transmissions, and medical X-rays may not seem all that similar, yet they are all forms of ...
