When a light ray moves from a denser to a rarer medium at an angle of incidence greater than the critical angle, it undergoes total internal reflection. This phenomenon occurs because the light ray cannot refract out of the denser ...
Diamond appears shiny primarily due to its high refractive index and strong dispersion of light. When light enters a diamond, it undergoes multiple internal reflections at different angles, enhancing its brilliance and sparkle. This phenomenon is known as diamond’s “fire” ...
The rainbow displays a continuous spectrum of colors. It typically shows seven distinct colors: red, orange, yellow, green, blue, indigo, and violet. This sequence of colors is formed due to the dispersion and refraction of sunlight through water droplets in ...
Cracked glass appears shiny due to reflection. When light encounters the cracked surface, it reflects off the irregularities, creating a shiny appearance. This reflection occurs because the smooth surfaces of the cracks act as mirrors, bouncing light back towards the ...
