Question

Why we cant see the light rays passing from tv remote?

Answer 1

Light moving at shoter or longer wavelengths than that does not excite our eyes ' sensors ,so we can't see it.

Our eyes can only see light in the ROYGBIV spectrum...

Answer 2

that is because the light is a energy and we cant see it.

But if you want to see the light you can use your phone camera to see the light (if the remote is working ofc)
