1) what is the image formed by a plane mirror if the incident beam is convergent? 2) how many majors are formed when two plane mirrors are inclined to tita with each other if the object is asymmetrically placed? 3) how many number of images are formed in symmetrical position ? 4) the laws of reflection change when the mirrors are indined at Tita angle with respect to each other ( true / false ) 5) what is the position called when the object is equidstance from the two mirrors inclined at Tita?
Answers
Answer:
1)When a convergent beam of light falls incident on a plane mirror, the image formed is Inverted and real. Inverted and virtual
Explanation:
2)If the image of an object is viewed in two plane mirrors that are inclined to each other, more than one image is formed. The number of images depends on the angle between the two mirrors.
The number of images formed in two plane mirrors inclined at an angle A to each other is given by the below formula.
Number of images n=
A
360
−1
The number of images formed n=
A =360
−1, if
A
360
is an even integer.
If
A
360
is odd integer, the number of images formed n=
A
360
−1 when the object is kept symmetrically, and n=
A
360
when object is kept asymmetrically.
If
A
360
is a fraction, the number of images formed is equal to its integral part.
As the angle gets smaller (down to 0 degrees when the mirrors are facing each other and parallel) the smaller the angle the greater the number of images.
