(a) The refractive index of glass is 1.5 . What is the speed of light in glass ? (Speed of light in vaccum is 3 xx 10^(8) ms^(-1) ). (b) Is the speed of light in glass independent of colour of light ? If not, which of the two colours, red and violet travels slower in a glass prism ?
(a) The refractive index of glass is 1.5. What is the speed of light in glass? (b) Is the speed of light in glass independent of the colour of light ? If not, which of the two colours red and violet travels slower in a glass prism?
Assertion: Speed of light in glass is indep[endent of the colour of light. Reason : the violet colour travels faster than the red light in a glass prism.
Light enters from air into a glass plate having refractive index 1.50 . What is the speed of light in glass? The speed of light in vaccum is 3 xx 10^(8) m s^(-1) .
A: The speed of light in water is not same as that in flowing water. R: The speed of light in water is not independent of the relative motion between the observer and the medium.
The refractive index of glass is 1.5. Calculate the speed of light in glass. The speed of light in air is 3.0 xx 10^(8) ms^(-1) .
A: Speed of light in a medium is independent of the motion of the source relative to the medium. R: Speed of light in a medium depends on the motion of the observer relative to the medium.
