Questions & Answers

Q: How can we calculate the velocity of light in water and glass based on their refractive indices?

To find the velocity of light in water and glass, we use the formula velocity = speed of light in air / refractive index, substituting the given values to calculate the velocities accurately.

Q: What are the refractive indices of water and glass with respect to air in the given problem?

The refractive index of water with respect to air is 1.3, and the refractive index of glass with respect to air is 1.5, as provided in the numerical problem.

Q: What units are used to express the velocity of light in water and glass?

The velocities of light in water and glass are expressed in meters per second, with the calculated values for water being 2.31 x 10^8 m/s and for glass being 2 x 10^8 m/s.

Q: How does the formula for refractive index help in calculating the velocity of light in different mediums?

By relating the speed of light in a medium to the refractive index, we can determine how light propagates through that medium, allowing accurate calculations of light velocity.

Summary & Key Takeaways

• Given refractive indices of water (1.3) and glass (1.4), calculate the velocity of light in both mediums.

• Formulas used: velocity of light in water = speed of light in air / refractive index of water, velocity of light in glass = speed of light in air / refractive index of glass.

• Velocity of light in water is 2.31 x 10^8 m/s, and in glass is 2 x 10^8 m/s.
