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.
What is the effect of light hitting a smooth, polished surface?
Specular reflection occurs, creating a clear, undistorted image.
What is the effect of light hitting a rough, irregular surface?
Diffuse reflection occurs, scattering light in many directions and creating a blurry image.
What happens if the angle of incidence increases?
The angle of reflection increases by the same amount, according to the law of reflection ().
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.
