Light Reflection Quiz

Study Notes

Law of Reflection: The angle of incidence (θi) is equal to the angle of reflection (θr).
Mirror Equation: 1/f = 1/do + 1/di, where f is the focal length, do is the distance between the mirror and the object, and di is the distance between the mirror and the image.
Types of Reflection:
- Specular Reflection: Mirror-like reflection, where the reflected light is parallel to the incident light.
- Diffuse Reflection: Scattered reflection, where the reflected light is scattered in different directions.

Snell's Law: n1sin(θ1) = n2sin(θ2), where n1 and n2 are the refractive indices of the two media, and θ1 and θ2 are the angles of incidence and refraction.
Refraction: The bending of light as it passes from one medium to another.
Total Internal Reflection: When light hits a medium with a lower refractive index at a shallow angle, it is completely reflected back into the original medium.
Critical Angle: The angle of incidence above which total internal reflection occurs.
Refraction through a Prism: The bending of light as it passes through a prism, which can separate white light into its component colors (dispersion).

Refractive Index: A measure of how much a medium bends light, dependent on the speed of light in the medium.
Optical Density: A measure of how much a medium slows down light, related to the refractive index.
Dispersion: The spreading of light into its component colors, due to different wavelengths being refracted at different angles.

Angle of Incidence equals Angle of Reflection: θi = θr, a fundamental principle of reflection.
Mirror Equation: A mathematical formula to calculate the focal length of a mirror, given by 1/f = 1/do + 1/di.
Types of Reflection:
- Specular Reflection: A mirror-like reflection where incident light is parallel to reflected light.
- Diffuse Reflection: A scattered reflection where incident light is reflected in different directions.

Snell's Law: A mathematical formula describing the relationship between refractive indices and angles of incidence and refraction, given by n1sin(θ1) = n2sin(θ2).
Refraction: The bending of light as it passes from one medium to another, caused by a change in speed.
Total Internal Reflection: A phenomenon where light is completely reflected back into the original medium, occurring when the angle of incidence is shallow and the refractive index decreases.
Critical Angle: The minimum angle of incidence required for total internal reflection to occur.
Refraction through a Prism: The separation of white light into its component colors (dispersion) due to different wavelengths being refracted at different angles.

Refractive Index: A measure of how much a medium bends light, dependent on the speed of light in the medium.
Optical Density: A measure of how much a medium slows down light, related to the refractive index.
Dispersion: The spreading of light into its component colors, caused by different wavelengths being refracted at different angles.
