🔗Related Concepts

Electromagnetic waves are oscillations of electric and magnetic fields that travel through space at the speed of light, encompassing a broad spectrum from radio waves to gamma rays. They do not require a medium to propagate and are fundamental to many technologies, including communication, imaging, and energy transfer.Electromagnetic Waves

Snell's Law describes the relationship between the angles of incidence and refraction when a wave passes through the boundary between two different media, governed by the formula n1*sin(θ1) = n2*sin(θ2), where n represents the refractive index of each medium. This law is fundamental in understanding how light bends when transitioning between materials, crucial for applications in optics and lens design.Snell's Law

Reflection and refraction are fundamental optical phenomena where light changes direction at a boundary between two different media. Reflection involves light bouncing back into the original medium, while refraction involves light bending as it passes into a new medium with a different refractive index.Reflection And Refraction
