Three beams of light 1, 2 and 3 of the same wavelength are sent through three different materials of refractive - Science - Light - Reflection and Refraction

Question

Three beams of light 1, 2 and 3 of the same wavelength are sent
through three different materials of refractive indices 1 60, 1 50
and 1 55 Arrange the velocity of these beams in different materials
in ascending order

Please explain the whole process in detail

We have relation,
Refractive index of a material=Speed of light in airSpeed of light in materialor Speed of light in material=Speed of light in airRefractive index of a materialThus, the speed of light will be greatest in the material having least refractive index
Ascending order of velocity is1<3<2

Three beams of light 1, 2 and 3 of the same wavelength are sent through three different materials of refractive indices 1.60, 1.50 and 1.55 . Arrange the velocity of these beams in different materials in ascending order. Please explain the whole process in detail.
