the refractive index of flint glass is 1.65.what is the speed of light in the glass?
speed of light in the air is 3 x 10 power 8 m/s.
Answers
The speed of light in the air is 3x10 power 8m/s.
This includes speed of light vaccum and refracted in the glass.
The refractive index should be included diamond as 2.42 and that includes glass of 1.81x10 raised to 8 power.
When light enters, it is having refractive index and happens in the glass.
Answer:
The Speed of Light in the Medium (Glass) is 1.8182×10⁸ m/s.
Explanation:
η (Refractive Index of a Medium) = c (Velocity of Light in Vacuum)/ν (Velocity of Light in the Medium)
Given values,
η is 1.65 (refractive index of glass)
c is 3×10⁸ m/s (speed of light in vacuum)
According to the above equation,
ν (Speed of Light in the Glass) = c (Speed of Light in Vacuum)/η (Refractive Index of Glass)
ν(Speed of Light in the Glass) = (3×10⁸ m/s)/1.65 = 1.8182×10⁸ m/s
ν(Speed of Light in the Glass) is 1.8182×10⁸ m/s.
