A well-cut diamond appears bright because

Options

  1. Ait emits light
  2. Bit is radioactive
  3. Cof its total internal reflection
  4. Dit has high density

Correct answer

C. of its total internal reflection

Step-by-step solution

As we know that, the refractive index of diamond is highest. And since, = 1 _c where, _C is critical angle and least. So, chances of total internal reflection will be highest inside diamond. Hence, diamond appears bright.
