When two soap bubbles of different diameters are brought in contact through a tube, they will adjust their sizes due to surface tension. The smaller bubble will grow larger, and the larger bubble will shrink to achieve equilibrium until they ...

The reason why we see the sun only a few minutes before the actual sunrise is due to refraction of light. Refraction bends light as it passes through the Earth’s atmosphere, causing the Sun’s image to appear above the horizon ...
The way to separate colors is by using a prism. When white light passes through a prism, it refracts differently based on wavelength, causing it to separate into its constituent colors—red, orange, yellow, green, blue, indigo, and violet—forming a spectrum.
White light is produced in a tube by heating a filament. The filament, typically made of tungsten, is heated to a high temperature by passing an electric current through it. This causes the filament to emit light across the visible ...
The reason for the elliptical appearance of the Sun and the Moon near the horizon is refraction. When these celestial bodies are close to the horizon, their light passes through a thicker layer of the Earth’s atmosphere, causing their image ...
Fiber optic used in communication works only on the principle of total internal reflection of light. This principle allows light to propagate through the fiber by continuously reflecting off the fiber’s walls, ensuring minimal signal loss over long distances.
The formation of a rainbow is due to the refraction, dispersion, and reflection of sunlight by water droplets in the atmosphere. Sunlight entering the droplets is refracted, split into its component colors, internally reflected, and then refracted again as it ...
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 ...
When a ray of light travels from a rarer medium to a denser medium, it gets bent towards the normal. This bending occurs because the light slows down in the denser medium, causing the direction of the ray to shift ...
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 ...
