a- the same
b- faster
c- slower
d- not measureable
ans) c- slower
the reason is that:
glass is optically denser,due to which the wavelength of light entering it decreases but frequency remains same,
due to this,its speed also decreases & it bends towards the normal.
A) the same. Glass is only a means of splitting the light into a component or resonant frequency, due, in the main to the oxides in the glass.
