if there are 2 mirrors kept parallel to each other they show infinite number of images

No.
There is the efficiency of the mirror's reflectance, which in reality is less than 100%. Eventually that would attenuate the bouncing light beam to nothing.
But even with two perfect mirrors, you couldn't have infinite reflections, because the speed of light is finite. The light has to bounce back and forth between the mirrors, and that takes time. For example, if the total zigzag light path of the umpteenth reflection is one light year, you'd have to wait a year to see that. To view infinite reflections, you'd have to wait an infinite amount of time for the light to get there. In other words, it never happens.

Real mirrors do not reflect an image perfectly. With each reflection, some of the light being reflected is absorbed, so even with the best mirrors, the number of reflections will be limited to some finite number.

The loss of image as described would be the real answer. An endlessly reflecting mirror would be a kind of perpetual motion machine. However there is another limit. When the image became smaller than the wavelength of visible light. The chance of hitting this limit is very close to zero, however, it is interesting.

Theortically yes. However during each reflection of the image , photons are lost till a point is reached where the image is blur and later it ceases. It is assumed here where the mirrrors are in a absolute vaccum and where the reflecting surface is 100 % efficient.
The degradation of image is much quicker on other mediums like air or water

Yes. Two parallel mirrors Will have infinity images reflected.
Cooment to tekguys answer.
Even if your mirrors are kept one mile a part you know how many images per hour and per day. That is close to infinity. SO you dont have to wait for a year.

No it can't because of the slight cant of the mirror to the angle of your eye in order for the reflection to pass the side of your face into the other mirror you are looking at this causes the endless corridor that disappears off to one side.

actually ,i mean theorotically,it shud,but it doesnt cos the mirrors we use are not 100%perfect reflectors they absorb some energy and thus the energy slowly decreases and becomes 0 after many reflections,in case of multiple mirrors.if only one mirror no possiblity of multiple reflections !!

if its a perfect mirror it wil allow infinite reflections.a perfect mirror is 1 whch allows all the light fallin on it to go back

As explained by others, mirrors not being perfect reflectors, absorb light and at some point of time, the intensity of light will decrease to an amount less than wat our eyes can perceive, infinite images will be formed, but our eyes will not be able to perceive them.
