The discussion clarifies that electromagnetic (EM) waves, specifically light waves, are not damped as they travel through space. Instead, their amplitude decreases due to the spreading of energy over a larger area, which results in fewer photons reaching an observer's eye at greater distances. The conversation highlights that collimated light sources, such as lasers, maintain intensity over long distances, further supporting the conclusion that intrinsic damping does not occur. The concept of "tired light" is mentioned as a reference point for understanding light behavior.
PREREQUISITESPhysicists, optical engineers, and anyone interested in the properties of light and electromagnetic waves, particularly in the context of visibility and distance perception.
Arup Biswas said:We can't see objects from objects far away from us. Why? I think light waves damps! When it reaches our eyes it's amplitude is too small to be visualised! Is this true? If indeed EM waves are damped then why? If not please give a suitable definition for the mentioned phenomena too !
