If the speed of light is `3.0xx10^(8)ms^(-1)`, calculate the distance covered by mass light in 2.00 micros.

If the speed of light is 3.0xx10^(8) m s^(-1) , calculate the distance covered by light in 2.00 ns .

The absolute refractive indices of glass and water are (3)/(2) and (4)/(3) respectively. If the speed of light is 2xx10^(8) m//s , calculate the speed of light in (i) vacuum, (ii) water.

The refractive index of glass with respect to water is 1.125 . If the speed of light in water is 2.25 xx 10^(8) ms^(-1) , what is the speed of light in glass ?

Light travels with a speed of 3xx10^(8) m s^(-1) . The distance travelled by light in 1 femto second is

The refractive index of glass is (3)/(2) and the refractive index of water is (4)/(3) . The speed of light in glass is 2.00 xx 10^(8) ms^(-1) . What is the speed of light in water in ms^(-1) ?

The speed of light in air is 3.00xx 10^8 m//s The distance travelled by light in one year (i.e.365 days = 3.154xx10^7s) is know as one light year. A student calculates one light year = 9.462xx10^(15) m. Do you agree with the student ? If not what should be the correct value of one light year?
