About 0.00005seconds in air. The spee of light in air is nearly 300000km/s. So, time required will be 15/300000 seconds which is 0.00005.

Since the speed of light is approximately 299,792 kilometers per second, it would take only around 0.00005 seconds to travel a distance of 15 kilometers at that speed.

What do you need to travel at the speed of light?

To travel at the speed of light, you would need to have an infinite amount of energy, which is currently not possible with our current technology and understanding of physics. Additionally, as per the theory of relativity, an object with mass cannot reach the speed of light.


What is quicker speed of sound or speed of light and why?

The speed of light is faster than the speed of sound. The speed of light in a vacuum is approximately 186,282 miles per second, while the speed of sound in air at room temperature is around 767 miles per hour. Light travels much faster because it does not require a medium to propagate, unlike sound waves which need a medium (such as air, water, or solids) to travel through.


What is its wavelength in Plexiglass where light travels at 67 percent of its speed in air?

To find the wavelength of light in Plexiglass, you need to take into account the change in speed of light. Since light travels at 67% of its speed in air in Plexiglass, you would need to calculate the wavelength using the formula: wavelength in Plexiglass = wavelength in air / refractive index of Plexiglass. Refractive index of Plexiglass is calculated as speed of light in air / speed of light in Plexiglass.


How meany pounds of force to get light speed?

To accelerate an object with mass to the speed of light, you would need an infinite amount of force, as the closer an object gets to the speed of light, the more energy it would need to accelerate further due to the laws of relativity. Additionally, as of our current understanding of physics, it is impossible for an object with mass to reach the speed of light.


What formula use to get the speed of light?

The formula used to calculate the speed of light is c = fΞ», where c is the speed of light, f is the frequency of the light wave, and Ξ» is the wavelength of the light wave. The speed of light in a vacuum is approximately 299,792 kilometers per second.

why speed of light is faster than speed of sound?

Actually, the speed of light is variable. Using diamonds and/or crystals, light-speed has been doubled as well as slowed to 30 mph.That being said, the waves that make sound are longer that the waves that make light, so they travel through air more quickly. Not so with water...See the related link below for more information:
