According to the law of reflection
Angle of incidence > Angle of Reflection
Angle of incidence < Angle of Reflection
Angle of incidence = Angle of Reflection
No relation between Angle of incidence and Angle of Reflection
Substances which allow light partially through them are called
Transparent Objects
Translucent Objects
Luminous objects
Non Luminous Objects
Virtual image is formed due to
Converging beam of light rays
Parallel beam of light rays
Diverging beam of light rays
An image which cannot be produced on a screen is called a virtual image.
Angle of incidence is equal to the angle of refraction
Always
Sometimes
Under special conditions
Never
The velocity of light in vacuum is
2x108 m/s
3x108 m/s
4x108 m/s
5x108 m/s
An instrument used in submarines to see objects on the surface of water, like ships is
Stethoscope
Microscope
Kaleidoscope
Periscope
The relation between u, v and f is
1/u - 1/v = 1/f
1/v – 1/u = 1/f
1/v + 1/u = 1/f
1/vu = 1/f
The image formed by a plane mirror is
Real
Virtual
Inverted
No image formation
The bending of light is called
Reflection
Diffraction
Dispersion
Refraction
The bouncing back of light after hitting on an object
Interference
