Question

find the refractive index of glass in which velocity of light is 2×10 power 8 m/sec.hint: velocity of light in air is 3×10 power 8 m/sec​

Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

Explanation:

$to \: find = \\ refractive \: index \: of \: glass \: (n) \\ \\ given = \\ velocity \: of \: light \: in \: air \: (V1) = 3 \times 10 {}^{8} \: m/s \\ velocity \: of \: light \: in \: glass \: (V2) = 2 \times 10 {}^{8} \: m/s$

$so \: we \: know \: that \\ refractive \: index \: (n) = \frac{V1}{V2} \\ \\ = \frac{3 \times 10 {}^{8} }{2 \times 10 {}^{8} } \\ \\ = \frac{3}{2} \\ \\ = 1.5 \\ hence \: n = 1.5$

$thus \: refractive \: index \: of \: glass \:in \: which \: velocity \: of \: light \: is \: 2×10 {}^{8} \: m/s \: is \: 1.5$
