has a greater amplitude than red light
is more intense than red light
travels more slowly than red light
deviates less than red light

Light has equal velocity 3.0 x 10^23 and yellow light has greater amplitude which causes a greater deviation from red light in a deviated spectrum of white light using a triangular prism
The correct answer is: C. travels more slowly than red light
Explanation: The refractive index of a material depends on the speed of light in that material. Light of different wavelengths (or colors) travels at different speeds when passing through a medium like glass. Yellow light has a shorter wavelength than red light, and in most materials, shorter wavelengths travel more slowly than longer wavelengths. This slower speed results in a higher refractive index.
So, since yellow light travels more slowly in glass than red light, it has a greater refractive index.
