The speed of light in vacuum is 3×108 m/s. Solution : Speed of light in vacuum (c) = 3 x 10 8 m/s. Refractive index = c/v. Speed of light in glass = 3 x 10 8 m/s/ 1.50. = 2 x 10 8 m/s. Checkout Class 10th Combos from PW Store. 9. Find out, from Table (10.3), the medium having highest optical density.
Nov 6, 2023 · NCERT Solutions for Class 10 Science Chapter 3 – Metals and Non-Metals. “Metals and Non-metals” is the focus of Chapter 3 in Class 10 Science. This chapter discusses the properties and reactions of various metals and non-metals. It covers topics like ionic compounds, the extraction of metals from ores, and their uses.
May 10, 2021 · The speed of light in vacuum is 3 x 108 ms-1. Answer. Refractive index of a medium, n m = Speed of light in vacuum/Speed of light in the medium. Speed of light in vacuum, c = 3 × 10 8 ms -1. Refractive index of glass, n g = 1.50. Speed of light in the glass, v = Speed of light in vacuum/ Refractive index of glass. = c/n g.
Direct the light reflected by the mirror on to a sheet of paper held close to the mirror. Move the sheet of paper back and forth gradually until you find on the paper sheet a bright, sharp spot of light. Hold the mirror and the paper in the same position for a few minutes.
