change in the path of light when passing from one medium to another
return of light into the same medium after striking a surface
Name the types of reflection seen
plain/ rough
irregular/regular
smooth/rugged

Define 'Normal'
light ray striking the reflecting surface
perpendicular drawn to the surface at the point of incidence
light ray obtained after reflection
A light ray is incident normally on a reflecting surface.The angle of reflection is (a)
The Laws of reflection are,
The normal is imaginary
The angle of incidence is equal to the angle of reflection
The image is virtual
The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.
Tick all the characteristics true for a real image
can be obtained on a screen
inverted with respect to the object
formed by a concave mirror for a distant object
cannot be obtained on a screen
formed by the actual intersection of the reflected rays
An image which cannot be obtained on a screen is called a (a) image
Characteristics of the image formed by a plane mirror
virtual
upright
same size as the object
laterally inverted
same distance behind the mirror as the object in the front of it
