An expression of snell's law from denser medium to rarer29) sinr> siniarer medium) sini > sinrเป็ sini = sinr |
|
Answer» If light travels from one medium with refractive index ni and incident angle i, to another medium with refractive index nr and refraction angle r, then the relationship is described by Snell's Law as such:nisin(i)=nrsin(r) which can be rewritten like this:sin(i)/sin(r)=nr/ni The case where light travels from a denser to rarer medium, then the only change would be that now ni>nr in which case the above equation would yield the index of refraction of the rarer medium in relation to the denser medium. (a) sini > sinr is correct option |
