JEE PHYSICS MCQ: RAY OPTICS

1 Medium

1 of 1

Understanding +4 | -1

The wavelength of light in air and some other medium are respectively

{\lambda _a}

and

{\lambda _m}

. The refractive index of medium is

View answer and explanation

Correct option: A

{\lambda _a}/{\lambda _m}

Option A (

{\lambda _a}/{\lambda _m}

) is correct because the refractive index is the ratio of the wavelength in air to the wavelength in the medium.
