The bending up of light when passing from one medium to another is known as
reflection
refraction
dispersion
none of these
The bending of light when it passes from one medium to another is called
Reflection
Refraction
Total internal reflection
Diffuse reflection
Among the given refractive index which one is more denser ?
1.2
1.25
2.4
3
The image which can be produced on a screen is called
Virtual image
Real image
Laterally inverted image
Diminished image
the fatter ( more curved ) a converging lens is
The shorter its focal length and more it magnifies
The longer its focal length and more it magnifies
The longer its focal length and less it magnifies
The shorter its focal length and less it magnifies
A person watching a fish in a fish tank, its size thus seen will be
big
small
not comparable
An ordinary mirror silvered at the back forms several images of one object due to
Multiple reflection inside the glass
At which condition total internal reflection takes place?
Angle of incidence > Critical angle
Angle of incidence = Critical angle
Angle of incidence < Critical angle
Angle of incidence = Angle of reflection.
The splitting up of light into its constituent colours is known as
Deviation
Dispersion
The converging lens in our eye will form a
Real inverted image on the retina
Virtual inverted image on the retina
Virtual erect image on the retina
Real erect image on the retina
