Question

Name the phenomenon shown in the figure.

a. Reflection
b.Refraction
c.Dispersion
d. Lateral Inversion


If two plane mirrors are inclined at the angle of 40 degree what is the number of images formed​

Answer 1

phenomenon is LATERAL INVERSION..

Answer 2

The answer to the given question is provided below:

1) The phenomenon shown in the figure is Lateral inversion (option d).

• The property of a plane mirror or flat mirror that is most noticeable for asymmetrical objects is lateral inversion.
• In this illustration, lateral inversion is demonstrated by the left segments of the alphabetical letter appearing as the right side section and vice versa.
• As a result, an alphabet's object and image are said to be laterally inverted.

2) Given:

The angle of inclination of two plane mirrors = 40°

To find:

The number of images formed by the mirror =?

Solution:

• The number of images formed by the mirror can be found by using the following formula:

    => Number of images formed (n) = 360°/ θ

    => Number of images formed (n) = 360° / 40°

    => Number of images formed (n) = 9 images - 1 (Since the integer is the odd number we need to subtract 1)

    ∴ n = 8 images

Hence, 8 images are formed by two inclined plane mirrors.
