In this lesson, we will learn how to describe the paths of light reflected from specular and diffuse surfaces, applying the law of reflection.
Q1:
Diffuse reflection involves light rays reflecting from an uneven surface, as shown in the diagram. The diagram shows four pointsβ π· , πΈ , πΉ , and πΊ βthat the three light rays π΄ , π΅ , and πΆ might possibly pass through after being reflected.
Which of the points would the light ray π΄ pass through?
Which of the points would the light ray π΅ pass through?
Which of the points would the light ray πΆ pass through?
Q2:
A light ray reflects from a mirror, as shown in the diagram. The length π΄ π΅ = 4 c m , the length π΅ πΆ = 4 c m , and the length πΆ πΈ = 5 c m . What is the length π· πΈ ?
Q3:
Specular reflection involves light rays reflecting from an even surface, as shown in the diagram. The diagram shows three pointsβ π· , πΈ , and πΉ βthat the three light rays π΄ , π΅ , and πΆ might possibly pass through after being reflected.
