uses of wavelength in color

[Bhuvanesh123]

red light has low frequency and high wavelenth

but the red light become less visibile after travelling .i mean cannot hit the wall which half kilometer from the source.

i need to know what changes in color with high frequency what changes in color with high wavelength

why it cannot hit the wall with same intensity as we seen at source

IS this a path loss question? or a reflectance question?

i need to know what changes in color with high frequency what changes in color with high wavelength

why it cannot hit the wall with same intensity as we seen at source

compared to all other visible lights we can see red light even at larger distances from its source as it has large wavelength
what do you actually mean by your last sentence ,is your question that why do color changes as frequency or wavelength changes?
