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 ...

Diffusion of light in the atmosphere occurs primarily due to the presence of dust particles. These microscopic particles scatter sunlight as it passes through the atmosphere, causing the sky to appear blue during the day and red or orange during ...
When a light ray passes from one medium to another, its frequency remains the same while its wavelength changes. The speed of light varies in different media, causing the wavelength to alter to maintain the constant frequency characteristic of the ...
The sky appears blue due to scattering of sunlight by air molecules and tiny particles in the atmosphere. Shorter wavelengths of light, particularly blue and violet, scatter more easily in all directions, making the sky appear predominantly blue during the ...
A compound microscope is an optical instrument designed for magnifying small objects. It uses multiple lenses to achieve high magnification. Light passes through the specimen and is magnified by an objective lens, then further enlarged by an eyepiece lens. This ...
