What happens when two mirrors face each other in a certain angle?

Depending on the angle between them, you will get multiple reflections of any object between the mirrors. If the mirrors meet at an angle of x degrees, an object placed between them should generate a maximum of (360/n) - 1 images. Parallel mirrors should, on that basis, produce an infinite number of images but because of microscopic flaws in the mirror, absorption, internal refraction etc, the images will degrade more or less exponentially.


How the angle between 2 mirrors affect the images formed?

How many images will be formed when a candle is placed between two plane mirrors at 40 cm's apart?

The answer depends on the angle between the mirrors. The distance between the mirrors does not, in theory, make any difference. If the angle between the mirrors is x degrees, then the theoretical number of images is (360/x)- 1 which is rounded down. In practice, minor defects in the mirrors, refraction, total internal refraction, absorptions, scattering etc will reduce the number of images.The answer depends on the angle between the mirrors.

What angles would you need between two mirrors to give you nine reflected images?

At angle of 30 two mirrors will give nine reflected images.


What do you understand by multiple images?

a number of images that are formed if the object is placed between two mirrors at an angle. This is called multiple images.


How many images are formed when two plane mirrors tilted an angle 72 degrees?

When two plane mirrors are tilted at an angle of 72 degrees, six images are formed. The first two images are the direct reflections from each mirror, and the remaining four images come from the multiple reflections between the mirrors.


What is the number of images formed by two plane mirrors when the angle between them is fifteen degrees?

23


What are three similarities between concave and convex mirrors?

Both concave and convex mirrors can create virtual images, which are images that cannot be projected onto a screen. Both types of mirrors follow the laws of reflection, with the angle of incidence being equal to the angle of reflection. Both concave and convex mirrors can be used in optical devices such as makeup mirrors or security mirrors.


What is the formula to find number of images formed when two plane mirror are inclined at an angle?

The number of images of an object placed between two mirrors inclined at an angle is give by:Number of images= (360/ angle of inclination)-1


What will happen if you put an object between two hinged mirrors and make the angle between them smaller?

The number of images increases


How many images will be seen if mirrors are put between 90 degrre angle?

360/90 - 1 = 4-1 = 3 images.


What will be the angle between two plane mirrors if 8 images of an object placed symmetrically are to be formed?

45 degrees.
