the speed of gamma radiation is higher than lower than same as visible light
In the electromagnetic spectrum, Gamma rays are the most energetic, with frequencies of 3*1019 Hz.
By the definition itself, visible light means we can see light and it has frequencies ranging from 4*1014 Hz to 8*1014 Hz.
Gamma rays wavelength : 10-10 -10-12 cm
visible light wavelength : ~ 10-5
Wavelength : Visible light > Gamma Rays
Frequency : Gamma Rays > Visible light.
Therefore the speed of Gamms rays is greater than Visible light. Because frequency means the no of waves passing through a point in a particular time (say in 1sec).
Please look at the electromagnetic spectrum of all the radiations and their corresponding properties.
Thank you and good luck.
