A diamond is underwater; A light ray enters one face of the diamond, then travels at an angle of 30 degrees with respect to the
normal. What was the ray's angle of incidence on the diamond? The index of refraction of water is nwater=1.33, and the index of refraction of diamond is ndiamond=2.42. Finally, apply Snell's law and find the ray's angle of incidence θ1 on the diamond.
<span>n1 sin theta1 = n2 sin theta2 </span>n1 = 1.333 (water) <span>n2 = 2.42 (diamond)</span> it is given that theta =30 degrees so by putting the values we have
The answer is not B or D because they need light co2 and water to make their food so B and D are out. and unless someone is walking during winter to feed it. It will not be A so the answer is C.
