In a chicken's eye, the retina has a large number of cones but only few rods. The rods are sensitive to bright light only. That is why a chicken is not able to see in dim light. As it needs bright light to see, so it wakes up early in the morning with the sunrise and goes to sleep by sunset.

Abhinav Raj Singh 1 year, 9 months ago

since the principal axis goes through the center of circle so line perpendicular to the principal axis from center of circle to the circumference of circle will form a line equal to half the height of object i.e 20cm(it is half because whple circle is 20+20 cm) so now we have ho=20 cm u= -30cm ( as mirror is 30cm away from center of circle) and f= -20cm by mirror formula :- 1/v+1/u=1/f =>1/v-1/30= -1/20 => 1/v= 1/30 - 1/20 => 1/v = 2-3/60 => v = - 60 cm now by magnification in mirror:- -v/u = hi/ho = m => -(-60)/(-30) = hi/20 =>-2 (20) = hi => hi = -40 cm so now the radius of crcle formed by image is equal to hi i.e radius of circle formed is 40cm
