A stone at the bottom of a pond appears higher than its actual position due to refraction of light. As light travels from water to air, it bends away from the normal, causing the stone to appear at a shallower ...

A fish lying inside water appears slightly above its actual depth due to the refraction of light. When light passes from water to air, it bends away from the normal. This bending causes the fish to appear at a shallower ...
A cut diamond sparkles due to its unique molecular structure. The facets of a diamond are designed to reflect and refract light internally, maximizing its brilliance and dispersion of colors, creating the sparkling effect known as “fire” in diamonds.
The bending of light from the core (edge) of a barrier is called diffraction. This phenomenon occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength, causing the wave to bend around ...
The first person to discover the speed of light was Ole Rømer. In 1676, he observed the eclipses of Jupiter’s moons and noticed a discrepancy in their timing, leading him to calculate the finite speed of light.
