Q1:

Diffuse reflection involves light rays reflecting from an uneven surface, as shown in the diagram. The diagram shows four pointsโ€” ๐ท , ๐ธ , ๐น , and ๐บ โ€”that the three light rays ๐ด , ๐ต , and ๐ถ might possibly pass through after being reflected.

Which of the points would the light ray ๐ด pass through?

Which of the points would the light ray ๐ต pass through?

Which of the points would the light ray ๐ถ pass through?

Q2:

Diffuse reflection involves light rays reflecting from an uneven surface, as shown in the diagram. The diagram shows three pointsโ€” ๐ท , ๐ธ , and ๐น โ€”that the three light rays ๐ด , ๐ต , and ๐ถ might possibly pass through after being reflected.

Which of the points would the light ray ๐ด pass through?

Which of the points would the light ray ๐ต pass through?

Which of the points would the light ray ๐ถ pass through?

Q3:
