Is speed of light least in kerosene?

Answer: We know from the definition of refractive index, that the speed of light is higher in a medium with lower refractive index. So, the light travels fastest in water relative to kerosene and turpentine.

What is the speed of light in oil?

Speed of Light and Matter

Material	Speed of Visible Light (m/s)
Glass	200 million
Vegetable oil	150 million
Alcohol	140 million
Diamond	125 million

Does light travel faster in water or kerosene?

Light travels fast in an optically rarer medium. If we consider the refractive of materials given in the options, we can see that the refractive index of turpentine is 1.525, the refractive index of water is 1.33 while the refractive index of kerosene is 1.35. So light will travel faster in water.

Which light travels fastest?

The wavelength of visible light increases from violet to red colour. It is highest for red colour. Hence, red colour travels fastest in any medium except air.

What is the speed of light in KM?

300,000 km/sec
Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

Which light travels faster?

Light will have the fastest velocity when it travels through the air.

Why is C the speed limit?

Einstein’s ultimate limit on speeds refers to the speed at which information can move from one point to another. Thus no physical particle can travel faster than c, lest information carried by that particle travel faster than c. This is why c is often called the ultimate speed limit of the universe.

WHO calculated the speed of light?

astronomer Ole Roemer
In 1676, the Danish astronomer Ole Roemer (1644–1710) became the first person to measure the speed of light. Roemer measured the speed of light by timing eclipses of Jupiter’s moon Io.

Which light has maximum speed in glass?

red color
So violet color has minimum velocity of light and red color has maximum velocity of light when it passes through the glass. Hence the red color of white light travels fastest in the glass.
