The Velocity of light in a diamond is (whereas the refractive index of a diamond with respect to vacuum is 2.5)?
ہیرے میں روشنی کی رفتار کیا ہے (جبکہ خلا کے حوالے سے ہیرے کا ریفریکٹیو انڈیکس 2.5 ہے)؟
Answer: 1.2x10^8m/s
Explanation
The velocity of light in a diamond is reduced due to the refractive index of the diamond. The refractive index (n) is related to the velocity of light (v) by the formula:
v = c / n
where c is the speed of light in vacuum (approximately 3x10^8 m/s).
Given the refractive index of diamond is 2.5, we can calculate the velocity of light in diamond as:
v = c / n = 3x10^8 m/s / 2.5 = 1.2x10^8 m/s
So, the correct answer is 1.2x10^8m/s!
