Solution
- Total internal reflection: The phenomenon due to which a ray of light, while traveling from an optically denser medium to an optically rarer medium, gets reflected into the optically denser medium, at the surface of separation is called total internal reflection.
- Air bubbles trapped in a glass paperweight appear silver due to the total internal reflection of light.
- Light rays strike the glass-air interface at an angle more than the critical angle of glass and get totally internally reflected thus imparting a silver color.
