You can see the wavelength of red light is greater than that of violet light. Since they both belong to the electromagnetic wave, their speed in vacuum both are 3 x 10 e 8. Please refer to
http://en.wikipedia.org/wiki/Speed_of_light
So their speed are equal in vacuum, air, glass and water.

你係講見到既紫光定係見唔到既紫外輻射先?

anyway...佢地都係屬於電磁波...速度都係等於光速...

唔同既係個頻率同波長姐....

上述全是小弟所知...希望幫到你
