Which of the following statement is not true for the electromagnetic waves? |
These waves have momentum These waves travel at different speeds in vacuum depending upon their frequency These waves transport energy These waves travel at different speeds in a medium depending upon their frequency. |
These waves travel at different speeds in vacuum depending upon their frequency |
The correct answer is Option (2) → These waves travel at different speeds in vacuum depending upon their frequency In vacuum, all EM waves travel at the same speed which is the speed of the light ($c=3×10^8m/s$), regardless of their frequency. |
