Answers
Answer:
Here it is
Explanation:
1) Join P'Q' and produce the straight line to meet at B. Measure ∠ABN = i and ∠CBN = r. It is found that ∠i = ∠r. This proves that Angle of Incidence is equal to Angle of Reflection.
2 ) The location of the image of a point object is as far behind the mirror as the object is in front of it.
3) Characteristics of the image formed by a plane mirror
The image formed is erect.
The image is laterally inverted.
The image is of the same size as that of the object.
The image is laterally inverted. ...
The image formed is as far behind the mirror as the object is in front of it.
4) The color appearance of an object depends upon the light which that objects reflects to the observer's eye. ... Practice A: No light will be reflected; it is all absorbed. Thus, the paper would appear black to an observer. Practice B: Red and orange will be reflected and so the paper appears reddish-orange to an observer.
