Study Notes
Plane Mirrors and Reflection
- A plane mirror is a flat mirror with a smooth surface that reflects light.
- The front surface of a plane mirror reflects most of the light incident on it.
Light Rays and Reflection
- An incident ray is a light ray that falls on a surface.
- Reflection of light is the change in direction of light when it bounces back from a surface.
- The angle of incidence is the angle at which an incident ray hits a surface.
Reflected Ray and Angle of Reflection
- The reflected ray is the light ray that bounces back from a surface after reflection.
- The angle of reflection is the angle at which the reflected ray bounces back from a surface, denoted by θr.
Types of Reflection
- Specular reflection is observed when light falls on a smooth and polished surface, resulting in a clear and undistorted image.
- Diffuse reflection is observed when light falls on a rough surface, resulting in a scattered and distorted image.
Laws of Reflection
- The law of reflection states that the incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane.
- According to the laws of reflection, the angle of incidence is equal to the angle of reflection (θi = θr).
Experiment to Verify Laws of Reflection
- In an experiment to verify the laws of reflection, a line AO is drawn such that ∠MOA is lesser than 90°.
- A plane mirror and a ruler are used to verify the laws of reflection in the experiment.
