Exploring the Speed of Light

What is the speed of light in a vacuum?

• 299,792 kilometers per second

• 150,000,000 meters per second

• 299,792,458 meters per second

• 300,000,000 meters per second

How does light speed change in water compared to air?

• Light speed decreases in water compared to air.

• Light speed is faster in water than in a vacuum.

• Light speed remains the same in water and air.

• Light speed increases in water compared to air.

Why does light travel slower in denser mediums?

• Light speed is constant regardless of the medium's density.

• Light travels faster in denser mediums due to less interaction with particles.

• Light travels slower in denser mediums because it interacts more with the particles in the medium, causing delays.

• Denser mediums have fewer particles, allowing light to move freely.

What is the formula to calculate the speed of light in a medium?

• v = n/c

• v = c + n

• v = c/n

• v = c * n

What is the refractive index of a medium?

• The refractive index is the angle of incidence of light in a medium.

• The refractive index is the ratio of the speed of light in vacuum to the speed of light in the medium.

• The refractive index is the temperature of the medium.

• The refractive index is the measure of light intensity in a medium.

How does the speed of light in diamond compare to that in air?

• The speed of light in diamond is slightly slower than in air.

• The speed of light in diamond is the same as in air.

• The speed of light in diamond is faster than in air.

• The speed of light in diamond is much slower than in air.

What happens to light speed when it enters a prism?

• Light speed increases and straightens when it enters a prism.

• Light speed decreases and bends when it enters a prism.

• Light speed remains constant and does not change direction in a prism.

• Light speed disappears completely when it enters a prism.

Can light travel faster than the speed of light in a vacuum?

• Light can travel at any speed depending on the medium.

• No, light cannot travel faster than the speed of light in a vacuum.

• Yes, light can travel faster than the speed of light in a vacuum.

• Light speed varies and can exceed the speed of light in a vacuum.

What is the speed of light in oil compared to water?

• Light travels at the same speed in both oil and water.

• Light travels slower in oil than in water.

• Light does not travel through oil.

• Light travels faster in oil than in water.

How does the speed of light affect communication technologies?

• The speed of light limits the speed of information transmission, affecting latency and the efficiency of communication technologies.

• Communication technologies operate faster than the speed of light.

• The speed of light has no impact on communication technologies.

• The speed of light enhances the quality of audio signals in communication.
