what is the velocity of the light in a glass with an index of refraction of 1.38
The reciprocal of 1.38 ?what is the velocity of the light in a glass with an index of refraction of 1.38
The Forum has TeX formatting with "Click and Write" functionality built in. In the editor, It is the Sigma at the left of the button bar: Ʃrefractive index = 1.38(glass)
refractive index = velocity of light in vaccum/velocity of light in medium
Velocity of light in vaccum = 3810^8 met/sec
--> 1.38 = 3*(10)8 / V
--> V= 3*(10)8/ 1.38
--> V = 21.73 * (10)7 met/sec
Hope its clear now..
cheers,
