• A. $ {{\upsilon }_{g}}>{{\upsilon }_{x}}=\,{{\upsilon }_{m}} $
• B. $ {{\upsilon }_{g}}<{{\upsilon }_{x}}<\,{{\upsilon }_{m}} $
• C. $ {{\upsilon }_{g}}>{{\upsilon }_{x}}>\,{{\upsilon }_{m}} $
• D. $ {{\upsilon }_{g}}={{\upsilon }_{x}}=\,{{\upsilon }_{m}} $

Answer 1

Answer: (D)

These are electromagnetic waves. We know that electromagnetic waves moves with speed of light.
