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:
What is the incident angle of the light ray shown in the diagram?
Q2:
Q3:
A light ray reflects from a mirror, as shown in the diagram. The length 𝐴 𝐵 = 4 c m , the length 𝐵 𝐶 = 4 c m , and the length 𝐶 𝐸 = 5 c m . What is the length 𝐷 𝐸 ?
Q4:
Diffuse reflection involves light rays reflecting from an uneven surface, as shown in the diagram. The diagram shows four points— 𝐷 , 𝐸 , 𝐹 , and 𝐺 —that the three light rays 𝐴 , 𝐵 , and 𝐶 might possibly pass through after being reflected.
Which of the points would the light ray 𝐴 pass through?
Which of the points would the light ray 𝐵 pass through?
Which of the points would the light ray 𝐶 pass through?
Q5:
Diffuse reflection involves light rays reflecting from an uneven surface, as shown in the diagram. The diagram shows three points— 𝐷 , 𝐸 , and 𝐹 —that the three light rays 𝐴 , 𝐵 , and 𝐶 might possibly pass through after being reflected.
Q6:
Specular reflection involves light rays reflecting from an even surface, as shown in the diagram. The diagram shows four points— 𝐷 , 𝐸 , 𝐹 , and 𝐺 —that the three light rays 𝐴 , 𝐵 , and 𝐶 might possibly pass through after being reflected.
Q7:
Specular reflection involves light rays reflecting from an even surface, as shown in the diagram. The diagram shows three points— 𝐷 , 𝐸 , and 𝐹 —that the three light rays 𝐴 , 𝐵 , and 𝐶 might possibly pass through after being reflected.
Q8:
The reflection of an object is seen in a mirror by an observer whose eye is shown in the diagram. At which of the points A, B, C, D, and E is the object’s image seen?
