1. • Transverse wave

     • Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).

   Light as a Wave. Reflection and Refraction. All waves exhibit both reflection and refraction properties. When a wave moves from one medium into another, its direction of propagation changes; this is termed refraction.

   Quick Facts: Electromagnetic Spectrum. Also known as: Electromagnetic radiation. Type: Radio, microwave, infrared, visible, ultraviolet, X-ray, and gamma ray. Size: We can describe light waves in terms of wavelength, or distance from one wave peak to the next.

   As a result, different models describe different aspects of light’s behavior. The electromagnetic wave theory explains light’s ability to travel through a vacuum. The light ray model, on the other hand, can describe interactions between light and matter.

   In all of these cases, light is modeled as traveling in straight lines called rays. Light may change direction when it encounters objects (such as a mirror) or in passing from one material to another (such as in passing from air to glass), but it then continues in a straight line or as a ray.

   If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.

8. People also ask

   How do you describe a light wave?

   • Size: We can describe light waves in terms of wavelength, or distance from one wave peak to the next. Each type of light has a different range of wavelengths. Radio waves are longest. Gamma rays are shortest. Did you know: Light can be converted from and into other types of energy, like sound and heat.

   What is the difference between electromagnetic wave theory and light ray theory?

   • As a result, different models describe different aspects of light’s behavior. The electromagnetic wave theory explains light’s ability to travel through a vacuum. The light ray model, on the other hand, can describe interactions between light and matter. Angle of incidence exceeds critial angle. Total internal reflection occurs.

   Do light rays follow a path after hitting a surface?

   • The path a light ray will follow after hitting a surface can be predicted based on the incident angle and information about the surface. Light rays that reflect follow the law of reflection. The law of reflection states that the angle of reflection * is equal to the angle of incidence. Light rays that pass through an interface are transmitted rays.

   What are the terms used to describe the behavior of light rays?

   • The following terms are used to describe the behavior of light rays: The light ray that hits a surface is the incident ray *. The angle it hits the surface is the angle of incidence. This angle is defined as the angle the incident ray makes with a line normal * (perpendicular) to the surface.

   What happens when a light ray encounters a surface?

   • When a light ray encounters a surface, one or more of the following three things occur, the light ray: Reflects off the surface and travels off in a different direction. Passes from one medium into the other and continue on a new, straight line path. Is absorbed. Often, more than one of these occur.

   Is light a wave or a particle?

   • Neither: light is its own unique phenomenon – the outcome of an interaction between electrical and magnetic fields – and it behaves like both waves and particles. Most of us were taught at school that light is a wave. This is because it does things that waves do. So, for example, waves undergo interference.
