WebImportant Questions for CBSE Class 10 Science Chapter 3 - Vedantu. The important questions on CBSE Class 10 Science Chapter 3 - Metals and Non-metals have been curated by our expert teachers in a manner that will allow students to explore the different kinds of problems that can be looked into based on the topics under this chapter. WebRefractive index by definition is inversely proportional to velocity of light in the medium. As temperature increases the density decreases so the photons can easily pass through the medium hence have higher velocity. This is similar to the fact that gases have lower refractive index compared to solids. 3 1 Gadi Lenz
