Light & Wave

다중 반사 (거울 2면)

Multiple Reflections

What is Image? Our eyes are designed to sense where the light started. Even if the light did not actually start there, our eyes say there is an ‘image’. There are a lot of ‘images’ when you look at the…

파동의 전파 Wave Propagation

Wave Propagation

In science, a wave is a phenomenon in which energy is transmitted through the medium. Only energy is transmitted through the waves. The medium that participates in the vibration only vibrates and does not actually move. Not all waves require…

Young’s Double Slit

The spacing and position of the slits can be adjusted. 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…

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.

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…
