(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 ...

It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different wavelength and frequency. Understanding the electromagnetic ...

A research team at Osaka University has successfully developed an ultra-compact microresonator device fundamentally different ...

Sub-wavelength optics is the study of light on a spatial scale smaller than its wavelength. Conventionally, the minimum length scale on which a beam of light can operate is equal to half its ...
