Explain the phenomenon of refraction in the context of physics and light.
Explain the phenomenon of refraction in the context of physics and light.
Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed. This change in speed is due to the change in the optical density of the medium.
Describe the properties and behavior of light as both a wave and a particle in the field of physics.
Describe the properties and behavior of light as both a wave and a particle in the field of physics.
In the wave theory, light exhibits properties such as diffraction and interference, while in the particle theory, light is composed of photons and exhibits behaviors like the photoelectric effect and Compton scattering.
Discuss the concept of total internal reflection and its practical applications in physics and optics.
Discuss the concept of total internal reflection and its practical applications in physics and optics.
Total internal reflection occurs when a light ray traveling from a denser medium to a rarer medium strikes the interface at an angle greater than the critical angle, causing the light to be completely reflected back into the denser medium. This phenomenon is utilized in optical fibers, prisms, and mirages.
