Compare specular and diffuse reflection.
Specular: Smooth surface, uniform reflection, clear image. Diffuse: Rough surface, scattered reflection, blurry image.
Differentiate between angle of incidence and angle of reflection.
Angle of incidence: Angle between incoming ray and normal. Angle of reflection: Angle between reflected ray and normal. They are equal.
Define a light ray.
A straight-line path that light travels in a specific direction, perpendicular to the wavefront.
What is the angle of incidence?
The angle between the incoming light ray and the normal (a line perpendicular to the surface).
What is the angle of reflection?
The angle between the outgoing (reflected) light ray and the normal.
Define specular reflection.
Reflection from a smooth surface where incident light reflects uniformly in a single direction.
Define diffuse reflection.
Reflection from a rough surface where incident light rays scatter in many different directions.
What are the differences between specular and diffuse reflection?
Specular: smooth surface, uniform reflection, clear image | Diffuse: rough surface, scattered reflection, blurry image.
Compare the surfaces that cause specular and diffuse reflection.
Specular: smooth, polished surfaces (mirrors, calm water) | Diffuse: rough, irregular surfaces (paper, fabric).
Compare the images formed by specular and diffuse reflection.
Specular: clear, undistorted images | Diffuse: blurry, scattered images.
Specular vs. Diffuse: Direction of reflected rays?
Specular: Reflected rays are parallel. | Diffuse: Reflected rays scatter in many directions.
Specular vs. Diffuse: Image clarity?
Specular: Clear image. | Diffuse: No clear image.
