The angle of incidence and angle of reflection in a plane mirror is :
Equal
Greater
Less
1/3rd of incident value
In lateral inversion:
Right of the object will be right side of the image
Left side of the object will be left side of the image
Upside of the object will be down side of the object
Right side of the object will be left side of the image
A device which works on the reflection of light from two plane mirrors arranged parallel to one another is:
electroscope
kaleiodoscope
periscope
stethoscope
The image formed by a plane mirror is:
virtual, behind the mirror and enlarged
virtual, behind the mirror and of the same size as the object
real,at the surface of the mirror and enlarged
real, behind the mirror and of the same size as the object
Which of the following is a non-luminous object?
sun
star
moon
fire
As the angle between two plane mirrors is decreased gradually, the number of images of an object placed between them:
increases gradually
decreases gradually
first increases then decreases
first decreases then increases
Which of the following is not a part of the human eye?
retina
auditory nerve
optic nerve
ciliary muscle
The part which protects the human eye is called:
Cornea
Chroid
Retina
Blind spot
When the distance between the object and the plane mirror increases:
the image remains same
the size of the image will become less than the size of the object
the distance between the image and the plane mirror increases
the distance between the image and the plane mirror decreases
Plane mirrors are arranged parallel to each other to get
A single image
Two images
A large number of reflected images
No image
