Question

Take two plane mirrors. Set them
at right angles to cach other with
their edges touching (Fig. 16.10). To
hinge them you can use adhesive
tape. Place a coin in between the
mirrors. How many images of the
coin do you see (Fig. 16.10)?
No. 16.10: Images in plane mirror ar right
angle to each other
Now hinge the mirrors using the
adhesive tape at different angles, say
45°, 60°, 1200, 180°, etc. Place some
object (say a candle) in between
them. Note down the number of
images of the object in each case.
Finally, set the two mirrors
parallel to each other. Find out how
many images of a candle placed
between them are formed (Fig.​

Answer 1

Answer:

see this a class 8th experiment number of images formed is given by 360/angle 360/45=8,360/60=6, in case of greater angle we reverse the proceedings that is 1200/360 and round it off to nearest that is 3,360/180=2

Explanation:

,

Answer 2

If two mirrors kept at 90 than 3 images will form.

If it kept at 120, 60, 45, 30 then 2, 5, 7, 11 images will form respectively.

if it kept at 180 then 1image will form.

Explanation:

As, number of images = 360÷angles between the mirror -1

therefore if angle is 90 then

360÷90-1=3

if angle is 30 then

360÷30-1=11

similarly we can find all angles
