Reflection: 

In geometric optics, reflection is reh bouncing back of light when it encounters a surface. 

There are two types of reflection: specular reflection and diffuse reflection.

1. Specular Reflection: 

• This type of reflection occurs when light rays strike a smooth and shiny surface, such as a mirror. 
  
• The incident light rays reflect off the surface in a regular and well-defined manner.
  
• The angle of incidence (the angle between the incident light ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected light ray and the normal). This principle is known as the law of reflection. 
  
• Specular reflection produces a clear and focused image, as it does not scatter light in different directions.
  

2. Diffuse Reflection: 

• This type of reflection occurs when light rays strike a rough or irregular surface, such as a piece of paper or a wall. 
  
• The incident light rays reflect off the surface in various directions, diffusing the light. 
  
• Unlike specular reflection, diffuse reflection does not follow the law of reflection, as the incident angle does not equal the reflected angle. 
  
• Instead, the light scatters in multiple directions due to the surface irregularities. 
  
• Diffuse reflection creates a soft and non-focused reflection, as it spreads the light in different angles.
  

It is important to note that the surface characteristics determine whether reflection is specular or diffuse. A smooth and polished surface will produce specular reflection, while a rough and irregular surface will produce diffuse reflection. Additionally, the type of reflection can impact the clarity and quality of the reflected image.
