Electromagnetic Waves: Seeing Objects and Colors. Visible light is a small part of the electromagnetic spectrum that the human eye is capable of seeing. When light strikes an object, it can be transmitted, reflected or absorbed. Reflection = when light bounces off a surface.

Wavelength: The distance between two consecutive peaks or troughs of a light wave. It determines the color of light - shorter wavelengths appear blue, while longer wavelengthsappear red.Frequency: The number of wave cycles that pass a given point in one second. It is inversely proportional to the wavelength.Speed: In a vacuum, light travels at a constant speed of approximately 299,792 kilometers per second.Reflection: The bouncing back of light when it encounters a surface, such as a mirror.Light can exhibit various behaviors, which include: 1. Wave-Particle Duality: The concept that light can behave as both a wave and a stream of particles called photons. 2. Interference: The interaction of two or more light waves, leading to the reinforcement or cancellation of the waves. 3. Diffraction: The bending of light wavesaround obstacles or...
Light has numerous practical applications in everyday lifeand in various scientific fields, including: 1. Optics: The study of light and its interactions with lenses, mirrors, and other opticaldevices. 2. Photography:The capture and manipulation of light to create images. 3. Medical Imaging: The use of light-based technologies such as X-rays, MRI, ...
