Answer 1

The lens parameter that enables us to brighten an image is called" Refractive Index"

What is refractive Index?

Refractive index of a material is a dimensionless number that describes how fast light travels through the material. Refractive Index is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.

Therefore, refractive index is the lens parameter that enables us to brighten an image.
