Young’s Double Slit

Young’s Double Slit experiment is a phenomenon in which light passing through two slits creates a specific pattern. Each slit acts as a source of coherent waves which spread out forming an interference pattern that can be seen on a…

Prism

The speed of light is about 300,000km/s. Light travels fastest in vacuum. As light passes through the material, the speed decreases slightly depending on the material. The speed of light reduction depends on the type or density of the material.…

두 파동의 중첩 Superposition

Superposition

Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. it creates constructive interference or destructive interference.

Superposition and Interference

Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. it creates constructive interference or destructive interference.

뉴턴 링 Newton Ring

Newton Ring

Newton rings are caused by the interference of two reflections. Newton Rings are observed when light is reflected from a plano-convex lens of a long focal length placed in contact with a plane glass plate. A thin air film is…

물방울에 의한 무지개 Rainbow by Raindrops

Rainbow by Raindrops

A rainbow is a natural phenomenon where the dispersion of light is most visible. As you know, a rainbow can be seen after it rains because the water droplets bend and disperse the light. For example, if we spray water…

회절 격자 Diffraction Grating

Diffraction Grating

The diffraction grating is a transparent plate with a very thin line on the surface. Light (photons) like to go in the same phase. In the same phase, constructive interference occurs. If the phases are different, the waves cancel each…

CD 표면의 무지개 색 Why does a CD reflect rainbow colors?

Why does a CD reflect rainbow colors?

Light (photons) like to go in the same phase. In the same phase, constructive interference occurs. If the phases are different, the waves cancel each other out. The light that passes through the hole in the diffraction grating has the…

편광 Polarization

Polarization

Polarizers are made of long chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The materials in the polarizing plate absorb only the electric field…

Electromagnetic Waves around of Visible Rays

Touch the screen to change the wavelength of the electromagnetic wave. Electromagnetic radiation refers to the waves of the electromagnetic field, radiating through space-time, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma…
