In which of the following situations could total internalreflection occur? Choose all that apply. Going from diamond to benzene.Going from hydrogen to fusedquartz. Going from water to crystallinequartz. Going from carbondioxide to diamond.Going from iceto carbon dioxide. Going from fusedquartz to ethylalcohol. Going from diamond to benzene.Going from hydrogen to fusedquartz. Going from water to crystallinequartz. Going from carbondioxide to diamond.Going from iceto carbon dioxide. Going from fusedquartz to ethylalcohol. Going from diamond to benzene.Going from hydrogen to fusedquartz. Going from water to crystallinequartz. Going from carbondioxide to diamond.Going from iceto carbon dioxide. Going from fusedquartz to ethylalcohol.

Explanation / Answer

for total internal reflection to occur light should move fromdenser to rarer medium. having more value of refractive index we can consider that asdenser medium refractive index of diamond = 2.41 refractive index of benzene=1.50 refractive index of hydrogen =1.000 refractive index of fused quartz =1.45 refractive index of water=1.33 refractive index of crystalline quartz=1.46 refractive index of carbon dioxide=1.000 refractive index of ice=1.31 refractive index of ethyl alcohol=1.362 so options 1 ,5,6 are correct. in all these cases light ismoving from denser to rarer medium.
