But how long does it take to get to mars? The speed of light c = 299792458 m/s ≅ 3 × 108 m/s. Speed of light the velocity of the light in the vacuum or air:

In terms of seconds, light travels at around 300,000 kilometers per second or 186,000 miles per second in a vacuum. What is the electromagnetic spectrum? Calculate the time taken by the light rays to cross the slab.
Mars is the most habitable planet in the solar system after earth.
Therefore, the amount of time it would take to get to jupiter really depends on how fast you. Light enters from air to kerosene having refractive index of 1.47. What is the speed of light in kerosene, if the speed of light in air is 3×108 m/s? The speed of light’s exact value is defined as 299.792.458 meters per second or approximately 300.000 km / 186.000 mi per second in a vacuum.
The ratio between the speed of light in medium to speed in a vacuum is the refractive index. The faster the speed of the spacecraft, and the more direct the route, the less travel time it takes. The velocity of light can be expressed in terms of mph or km/s. The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 10 25 hz,.
A light ray falling at an angle of 60∘ with the surface of a clean slab of ice of thickness 1.00 m is refracted into it at an angle of 15∘.
When the light ray is travelling in air entering into water obliquely, the light ray bends towards the normal because water as a medium has an optically denser medium than air. Click for even more facts and information.
