What is the speed of light in a medium of refractive index 2?

Refractive index (n)= c/v, where c is the velocity of light in a vacuum ( 3 × 108 m/s) and v is the velocity of light in a substance….Detailed Solution.

Medium Refractive index Speed of light (m/s)
Glass 1.5 2 × 108
Diamond 2.4 1.2 × 108

What is the refractive index of a material with respect to air if speed of light in that medium is 108 m/s *?

The speed of light in air is 3.0 x 108 m/s. The refractive index of glass is 1.5.

What is the refractive index of glass if the speed of light in glass is 2×108 m s?

REFRACTIVE INDEX = 3/2.

What is the speed of light in glass if the absolute refractive index of glass is 1.5 and speed of light in vacuum is C?

Hence, the speed of light in glass is 2 × 108 m/s.

How do you find the speed of light in a medium?

The speed of light in a medium is v=cn v = c n , where n is its index of refraction. If we divide both sides of equation c = fλ by n, we get cn=v=fλn c n = v = f λ n .

What is the speed of light in a medium of index of refraction n?

The refractive index of a medium (n) is equal to the speed of light (c) divided by the velocity of light through the medium (v). Rearranging the equation allows us to see the relationship regarding v. The lower the refractive index, the faster the velocity of light. Medium A has the smaller refractive index.

What is the speed of light in glass?

200,000 kilometers per second
Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second in glass (refractive index of 1.5).

How do you calculate the speed of light in glass?

The speed of light in a material is slower than it is in vacuum. It is calculated using the index of refraction of the material. Typical window glass has an index of refraction n=1.5. The speed of light is given by v = c/n = 300000km/s / 1.5 = 200000 km/s.

What is the speed of light in glass formula?

To find the speed of light of a medium, use the equation v = c/n , where c is the speed of light in a vacuum.

What is the speed of glass?

For glass, the speed of sound is about 4 to 5 kilometers per second, but the Slow Mo Guys recorded crack propagation speed at just under 1.5 kilometers per second.
