Please only answer question 9. I included question 8 as well to give the background of the question. Please give a detailed explanation for why the total internal reflection occurs when the incident angle is greater than the critical angle. Please explain each step carefully with good reasoning. The refraction indices of materials vary slightly with temperature and with the wavelength of the light goingthrough the material. The index of refraction of water at 70°C for a helium neon laser is 1.32 = (use thefraction-no calculators). If the laser is shone through a right triangular prism of water (held by in place bynegligibly thin walls) as drawn,8. What is the critical value of the angle of incidence, e;, such that beyond this angle, the laser is not transmittedthrough the far side as indicated?9. Does total internal reflection occur for incident angles greater than or less than 0;, ?

Total internal reflection will occur at two specific conditions 1) when the light travels from a denser medium to a rarer medium 2)when the angle of incidence is greater than the critical angle for that particular mediumWhen a light travels from a denser medium to a rarer medium the refracted ray bends away from the normal, if the angle of incidence is increased the angle of refraction will keep on increasing and at a certain angle of incidence, the refracted angle will become perpendicular to the normal μ=sin θisin θr at θi=θi.c and θr=90°μ=sin θi.c When θi>θi.c, no more refraction takes place instead total internal reflection takes place
