1)I know that light with more wavelength run faster in the glass from an other with less.But why? If you tell me because has less diffract I will ask again,why it has less?
Light travels slower in glass due to the interaction between the light and the molecules in the glass. The molecules absorb and re-emit the light, causing it to take longer to travel through the material.
The wavelength of light plays a significant role in its speed in glass. Light with shorter wavelengths, such as blue or violet light, will travel faster in glass compared to light with longer wavelengths, such as red or orange light.
The velocity of light in glass is inversely proportional to its wavelength. This means that as the wavelength decreases, the velocity of light increases in glass.
The refractive index of glass is a measure of how much slower light travels in the material compared to in a vacuum. The higher the refractive index, the slower the speed of light in glass. This is because a higher refractive index indicates a stronger interaction between light and the molecules in the material.
Yes, the speed of light in glass can be altered by changing the properties of the glass, such as its composition or temperature. This can also be achieved by using specialized materials, such as metamaterials, which can manipulate the speed of light in unique ways.
