If the radiation is absorbed by a surface, the momentum drops to zero and a force is exerted on the surface |
the electromagnetic wave must have the following properties: 1 The field pattern travels with speed c speed of light ; 2 At every point within the wave.

It was found that the eye could respond to radiation at wavelengths at least as far as 1064 nm.
