Reflection of light is the bouncing back of light rays from a surface.
What is refraction of light?
Refraction of light is the bending of light rays when they pass from one medium to another.
What is the law of reflection?
The law of reflection states that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
What is the angle of incidence?
The angle between the incident ray and the normal to the surface at the point of incidence is called the angle of incidence.
What is the angle of reflection?
The angle between the reflected ray and the normal to the surface at the point of incidence is called the angle of reflection.
What is the normal?
The normal is a line drawn perpendicular to the surface at the point of incidence.
What is the speed of light in vacuum?
The speed of light in vacuum is approximately 3 × 10^8 meters per second (m/s).
What is the speed of light in air?
The speed of light in air is approximately the same as the speed of light in vacuum.
What happens when light travels from a rarer medium to a denser medium?
When light travels from a rarer medium to a denser medium, it bends towards the normal.
What happens when light travels from a denser medium to a rarer medium?
When light travels from a denser medium to a rarer medium, it bends away from the normal.
What is the refractive index of a medium?
The refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium.
What is the formula for calculating refractive index?
Refractive index (n) = Speed of light in vacuum (c) / Speed of light in the medium (v)
What is the phenomenon of dispersion of light?
Dispersion of light refers to the splitting of white light into its constituent colors when it passes through a prism.
What are the colors of the visible spectrum?
The colors of the visible spectrum are red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).
What is the critical angle?
The critical angle is the angle of incidence that produces an angle of refraction of 90 degrees.
What is total internal reflection?
Total internal reflection is the phenomenon that occurs when the angle of incidence is greater than the critical angle, causing all the light to be reflected back into the original medium.
