{v_{2}}\) then: \(n=\frac{v_{1 ... where the light is faster (ie bigger speed), the angle is bigger and the wavelength is bigger. A ray of blue light of frequency \(4.8 \times {10^{14}} ...

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 ...

The types of radiation that occur in different parts of the spectrum have different uses and dangers - depending on their wavelength and frequency. The speed of electromagnetic waves in a vacuum ...
