Time taken by the light ot travel through 5 cm orf glass is same is 1.5, then x cm of air. Irf R.I. of glass is 1.5, then x is

The time taken by a ray of light to travel through 5 cm of glass is the same as that through x cm of air. If the R.I. of glass is 1.5 , then the value of x is

Calculate time taken by light to travel 1 cm thickness of glass of mu = 1.5 .

The optical path of a monochromatic light is the same if it travels through 4 cm of glass or 4.5 cm of water . If the refractive index of galss is 1.5, then the refractive index of water is

Time taken by sun light to travel through a glass slab of thickness 5mm whose refractive index is 1.5 in sec is

The time taken by a ray of light to travel through a glass slab of thickness 2 cm and refractive index 1.5 will be

The optical path of a monochromatic light is same if it goes through 4.0 cm of glass or 4.5 cm of water. If the refractive index of glass is 1.53, the refractive index of the water is
