An air bubble in water behaves like a convex lens. It causes light rays passing through it to converge, forming a virtual image due to refraction. This effect is similar to how a convex lens refracts light to converge at ...

Total internal reflection occurs when light travels from a denser medium to a rarer medium, with an angle of incidence greater than the critical angle. This phenomenon causes the light to be completely reflected back into the denser medium, rather ...
A stick immersed in water appears bent due to the refraction of light. When light travels from water to air, it bends at the interface. This bending alters the apparent position of the stick, making it look bent at the ...
A spherical air bubble embedded in glass behaves optically like a converging lens. Due to the curvature of the bubble’s surfaces, it causes light rays passing through it to converge, similar to how a convex lens bends light towards a ...
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 ...
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.
