If the angle between two mirrors is 180°,how many images will be formed?
1
2
3
many
The nature of image formed on the retina of human eye is :
Virtual and erect
Virtual and inverted
Real and erect
Real and inverted
Plane mirrors are arranged parallel to each other to get
A single image
Two images
A large number of reflected images
No image
If the angle of incidence is 50°, then calculate the angle between the incident ray and the reflected ray ?
50°
100°
130°
An incident ray makes an angle of 650 with the surface of a plane mirror. The angle of reflection in this case will be:
650
450
250
350
The E.N.T. doctor uses a
Convex mirror
Convex lens
Plane mirror
Concave mirror
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
The outer layer of the eye is called:
Cornea
Sclerotic
Choroid
Retina
Which type of mirrors are used in telescopes for reflecting light ?
Concave mirrors
Convex mirrors
Plane mirrors
Convex lenses
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
