Properties of a plane mirror
Question:
3
m.
Fill ups:
1
.
The image formed by a plane mirror is
virtual but can be projected on a screen using a lens
real and always formed behind the mirror at a fixed distance
virtual and cannot be obtained on a screen as rays only appear to meet
real and can be obtained on a screen because reflected rays actually meet
2
.
The phenomenon in which left and right sides of the image are reversed is called
lateral inversion where left becomes right and right becomes left
complete inversion where the image is turned upside down
vertical inversion where the top and bottom of the image are interchanged
reflection inversion where the image rotates through 180 degrees
3
.
A plane mirror obeys the
laws of refraction because light changes medium after reflection
laws of reflection where incident ray bends into the next medium
principles of scattering as light spreads in all directions
laws of reflection where incident ray bounces back into the same medium
