The index of refraction of diamond is 2.4. Find the smallest incident angle for which a light ray going from diamond to air is totally reflected (the critical angle). This is why cut diamonds “sparkle”.

A beam of white light is incident on the surface of a diamond at an angle θa. (Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. For example, the indices of refraction in diamond are nred=2.410 for red light and nblue=2.450 for blue light. Thus, blue light and red light are refracted at different angles inside the diamond, as shown in...

15 Diamond has an index of refraction of 2.42, and part of the reason diamonds sparkle is that this encourages a light ray to undergo many total internal reflections before it emerges. (a) Cal culate the critical angle at which total internal reflection occurs in diamond. (b) Explain the interpretation of your result: Is it mea- sured from the normal, or from the surface? Is it a minimum angle for total internal reflection, or is it a maximum? How would...

The Ocrit angle is= 24.09 degrees
A beam of white light is incident on the surface of a diamond at an angle 02. (Figure 1) The index of refraction actually depends on the light's wavelength, so the different colors that comprise white light will spread out as they pass through the diamond (like in a prism). The index of refraction in diamond is nblue = 2.450 for blue light while the indices of refraction for the lower frequency colors are...
