The speed of light in glass having refractive index of 1.5=……………….`ms^-1`.

In an ideal double slit experiment when a glass plate having refractive index 1.5 and thickness t is placed in the path of interfered light rays of wavelength lambda then the intensity remains unchanged at the place where the central maximum was previously formed. Then the minimum thickness of the glass plate is

What is the Brewster angle for air to glass transition? (Refractive index of glass = 1.5.)

Light enters from air to glass having refractive index 1.50 what is speed of light in glass? Speed of light in vacuum is 3xx10^8 m s^-1 .

Green light of mercury has a wavelength 5*5 xx 10^(-5) cm. What is the wavelength in glass,if refractive index of glasss is 1.5?Given, c=3 xx 10^8 m s^(-1) .

Light travels through a glass plate of thickness t and having a refractive index mu .If c is the velocity of light in vacuum,the time taken by the ligth to travel this thickness fo glass is
