Refraction - Snell's Law
Image from http://www.gcsescience.com/pwav23.htm Normal- line at 90 degrees to surface i- angle of incidence r- angle of refraction n-refractive index sini/sinr=n This is always in air/in medium Refraction occurs when light passes from one medium to another. This is a change in speed which results in a change of direction The higher the refractive index, the more refraction occurs Speed of Light in air- 3x10^8m/s Speed of light in glass- 2x10^8m/s v=fλ Frequency remains constant when passing between mediums f- frequency (Hz) v- velocity (m/s) λ- wavelength (m) Critical Angle- the angle at which total internal reflection occurs. For glass-41.8 degrees n= 1/sinc
Appreciated.
Just finished my website!
The whole of the higher physics course is on there for people who need it for revision next year:
