Is it simply a product of the cell walls intrinsic light permeability that causes green light to reflect? Or is green light just intrinsically useless as a form of energy? It just seems strange to me that plants can photosynthesize with short and long wavelengths but not green which is in the...

Thank you for replying guys I've learned something new from both of your replies so thank you for enlightening me!

In your analogy is each child in the backseat a different frequency / colour of light? Also what would the car be analogous with?

Plant leaves only appear green because they absorb the red and blue wavelengths of light and reflect green away. Is there an intrinsic and innate reason for this that relates to the physics of light? Maybe green wavelengths are inefficient at storing energy in chemical bonds? Have plants simply...

We know the speed of light is a constant but speed is just the measure of distance over time. If blue light has a shorter wavelength than red but covers the same distance / time does this mean that blue light has actually made a longer journey than red light in order to arrive simultaneously? I...

Hi all thanks for the detailed and varied replies to my very flawed question! I realized as soon as I posted that there are an almost infinite variations on the basic seven colours. It's like asking how long is a piece of string 🤣😭

Summary:: If relativity causes wavelengths to change I.e the redshift effect (or blue shift effect for objects moving towards us) does the presence of 7 different colours denote seven different changes? If the doppler effect shows that direction of trajectory changes wavelength and colour of...
