The refractive index of glass is 1.5 and that of water is 1.3. If the speed of light in water is `2.25 xx 10^(8) m///s`, what is the speed of light in glass ?

Text Solution

AI Generated Solution

To find the speed of light in glass, we can use the relationship between the refractive index and the speed of light in different media. The refractive index (μ) of a medium is defined as: \[ \mu = \frac{c}{v} \] where: - \(c\) is the speed of light in vacuum (approximately \(3.00 \times 10^8 \, m/s\)), ...
