Question

1. In the first experiment, you’ll be making measurements on three sets of incident and
refracted rays passing into, through, and out of a block of translucent acrylic (plastic)
with a known refractive index of 1.49. Do you think the refracted rays will be bent
towards the surface normal when they enter the block, or away from it? Or will it depend
upon the angle of incidence? Explain your thinking.
2. In the second experiment, you’ll be shining a laser beam through sidebyside
“blocks” of
water and cooking oil. Will you have to shine the laser beam through the oil first, or
through the water first, in order to obtain total internal reflection? Explain your
reasoning.

Explanation / Answer

2) When light ray travels from denser medium to rarer medium for a certain angle of incidence called critical angle there will be total internal reflection lf light with out any refraction refractive index of water is 1.33 and refractive index of cooking oil is 1.47 so out of then cooking oil is denser than the water so when light ray travels from cooking oil tto water for a particular angle of incidence total internal reflection can be observable AS per CRAMSTER there should be only one question per post so please post other questions seperately AS per CRAMSTER there should be only one question per post so please post other questions seperately
