Refraction: change of wavespeed Refraction through a rectangular glass block Refraction is evidence of the wave nature of light We can only explain refraction in terms of waves. Wavespeed changes when a wave moves from one medium to another. (See here for more detail). That is what makes the wave refract. Refraction of light

Now revise the topic from flash cards I have written for:
Refraction may be our route to invisibility... See the page on refraction wavespeed changes and the page on Snell's Law (A Level only) LOJ October 2002 amended March 2003 |
