Question

A beam of light consisting of red, green, and blue colors is incident on a right-angled prism. The refractive indices of the material of the prism for the above red, green, and blue wavelengths are 1.39, 1.44, and 1.47, respectively. The prism will

• A. separate part of the red color from the green and blue color
• B. separate part of the blue color from the red and green color
• C. separate all the three colors from one another
• D. not separate even partially any color from the other two colors

Answer 1

The correct option is A separate part of the red color from the green and blue color

The prism will separate part of the red color from the green and blue color as the refractive index are different hence they undergo different deviations
hence correct option is $A$.
