प्रश्न

Choose the correct answer from given options
The relationship between Brewster angle θ and speed of light v in the denser medium is

पर्याय

  • c cosθ = v

  • v tanθ = c

  • c = v tanθ

  • v cosθ = c

MCQ

उत्तर

Disclaimer: Two of the given option (b and c) are same.
Let the absolute refractive index of the given medium be μ and the speed of light in vacuum be c.

From Brewster's law:
`tan theta = mu`
The refractive index can also be written as:
`mu = c/v`

⇒ `tan theta = c/v`

⇒ `c = v tan theta`
Hence, the correct answer is option v tanθ = c.
