Answer 2

n, wavelength /u and v/u

Explanation:

Refraction at a plane surface :

uv=constant and u wavelength = constant

where u is the refractive index, v is the velocity, wavelength(--) is the wavelength

Hence the answer is n, wavelength/u and v/u

Please write wavelength sign instead of writing wavelength...
