Answer A is right , because c. = frequency×wavelength
that means red light will have larger speed since it has larger wavelength
also c is inversely proportional to refractive index
Hence red light will be slower in this given glass than violet
that means red light will have larger speed since it has larger wavelength
also c is inversely proportional to refractive index
Hence red light will be slower in this given glass than violet

The refractive index of glass is 1.5 which of the two colors red and v...
The refractive index of a medium is a measure of how much the speed of light is reduced when it passes through that medium. In the case of glass, the refractive index is 1.5.
When white light passes through a glass prism, it undergoes dispersion, which means that it separates into its constituent colors. This is because different colors of light have different wavelengths, and thus different speeds in a medium.
In the case of a glass prism with a refractive index of 1.5, the speed of light is reduced by a factor of 1.5.
Now, let's consider the red and violet components of white light separately:
- The red component of white light has a longer wavelength compared to the violet component. As a result, it has a lower frequency and travels slower in a medium. This is because the speed of light is inversely proportional to its wavelength in a medium.
- On the other hand, the violet component of white light has a shorter wavelength, higher frequency, and travels faster in a medium.
Thus, based on the relationship between the wavelength and the speed of light in a medium, we can conclude that the violet component of white light travels slower than the red component in a glass prism.
Therefore, the correct answer is option 'D': the violet component of white light travels slower than the red component in a glass prism.
