12.Regular mirror are actually a plane mirror i. e. a mirror without inward and outward
curves. These mirrors can be found almost anywhere from bathroom to hallways to building
exteriors. Plane mirror creates an upright, virtual and laterally inverted image of the same
size as the object and at the same distance as the object. The ratio of the size of the image
to the size of object is termed as the ‘magnification’
Plane mirror produces a magnification of.
a) 1 b) 3 c) 2 d) 4
II) If a person of height 1.45 metre stands in front of a plane mirror, he/she would get an
image as height as.
a) 1.45 cm b) 1450mm c) 1.45mm d) 14.5 cm
III) A car is parked roadside, A truck passes it at a speed of 5 metre /second. What would be
the speed at which the image of the car appear to move away from the truck has viewed in
the rear view mirror of the truck.
a) 1 m/s b) 2.5 m/s c) 5 m/s d) 10 m/s
IV) A person has height 1.5 what is the size of plane mirror to observe full image.
a) 1.5m b) 0.7 5 m c) 3.0 m d) any size.
V) A person is moving in front of mirror with Speed 2 m/s. What is the speed of image
observed by a person with respect to mirror?
