Answer 1

Answer:

Two plane mirrors kept at 60° form 5 images of an object kept between them.

 Explanation:

Number of images formed when two plane mirrors are kept at an angle q degrees is:

360 ​ /q  −1

i.e., 60 /360 ​−1=6−1=5

Answer 2

Answer: The correct answer is 5 images.

Two plane mirrors are kept at 60 degree will form 5 images of an object kept between them.

Explanation:

• A surface is considered to be a mirror in the field of physics when it has the ability to reflect practically all forms of light that strikes it.
• In addition, a mirror will continue to reflect light in a consistent manner until or unless an opaque item is placed between the reflecting surface and the source of light.
• In this case, the mirror will stop reflecting light.
• The number of images that are created when two plane mirrors are angled to one another at θ degrees is:

$\frac{360}{\theta}-1 = n$ where n is number of images

$n= \frac{360}{60}-1\\n = 6 - 1\\n =5$

• Two plane mirrors are kept at 60 degree will form
• 5 images
• of an object kept between them.
