The number of images formed (n) depends upon the angles between them (θ) as
n = (360° /θ) -1
now, in this case as the mirrors are placed parallel to each other, θ = 0°
So, n = (360/0) - 1 = infinity
thus, number of images will be infinite.

Celestial objects which revolve in elliptical orbit around the earth are called COMETS

0Thank You

Yogita Ingle 7 years, 1 month ago

Comets also orbit the Sun and are relatively small bodies of the solar system. When comets approach the sun, some part of their ice melts. When some part of the ice melts, the other materials vapourise due to the heat of the sun. This results in a glowing halo that extends outwards as though sailing through space. The ice and compounds like ammonia and methane develop a fuzzy cloud like shell known as the coma.

Gaurav Seth 7 years, 1 month ago

Stars in the sky appear to be moving because of the rotation of earth on its axis. Earth moves from west to east. Therefore, it appears as if stars are rising in the west and as day dawns they set in the west.

So, stars are relatively in motion with respect to the roation of Earth.
