Question

How
many
images
of
a
candle
will
be
seen
when
two
mirrors
are
set
parallel





























to
each
other
and
a
candle
is
placed
between
them?​

Answer 1

Object placed between two parallel plane mirrors form infinite images. Hence, infinite images of the candle will be formed.

Answer 2

Concept Introduction: Light/Optics

Answer: Infinity (∞)

Explanation:

• When two plane mirrors are parallel then angle between them zero.
• By using simple formula for plane mirrors to calculate the number of images

                       When the two mirrors are at an Ф angle,

                       The number of image is given by,

    Number of image,

                            →       $\frac{360}{Angle}-1$,

Here angle Ф is zero then

                            →         $\frac{360}{0}-1=infinity$ (∞)

• When the two Mirrors are placed parallel to each other then Number of Images will be Infinite.

Hence, the correct answer of the Question is Infinity.
