Important Questions from Refraction of light
Which of the following are laws of refraction? (Select all correct answers)
Show answer
Incident ray, refracted ray and normal are in the same plane, sin i / sin r = constant for given pair of media
The two laws of refraction state that: 1) The incident ray, refracted ray and normal are coplanar, and 2) The ratio sin i/sin r is constant (Snell's law).
When light goes from a rarer to a denser medium, it:
Show answer
Bends towards the normal
When light passes from a rarer medium (lower refractive index) to a denser medium (higher refractive index), it bends towards the normal.
The separation of white light into seven colors is called:
Show answer
Dispersion
Dispersion is the process of separation of white light into its component colors when it passes through a medium like a prism.
Which color bends the most during dispersion?
Show answer
Violet
Violet light has the shortest wavelength and highest frequency, so it has the highest refractive index and bends the most during dispersion.
