Absorption

Quick Question:

Something appears to look violet, because the material absorpts every spectral colors with exception of violet of course.

So why is material with violet surface heating-up faster than a material with yellow surface?

i think this has to do with the reflectivity and darkness of the object. violet is darker thus it reflects less light.

Explanation from someone not into physics:

Recall that lower wavelength connotes higher frequency. And that higher frequency entails higher energy. Yellow is at a higher wavelength (~600 nm, perhaps) than violet is (~400 nm). So a violet object is heating up faster because it has higher energy than a yellow object.

uhh.... no.

kinetic energy is proportional to velocity.
velocity is equivalent to wavelength multiplied by frequency.
If you lower the wavelength and raise the frequency, git would look something like this:

Pre:  Wavelength = 1.  Frequency = 1.
Velocity = λ*f = 1*1 = 1

After raising F, lowering wavelength:
Wavelength = .5   Frequency = 2
Velocity = λ*f = .5 * 2 =1

1=1!!! omfg you didnt do shit!

8/10, I bothered typing a response.

Planck relation: E = hf

The photon energy is dependent on the frequency, not the wavelength.

It's an effect similar to osmosis - the sun is yellow, the surface is yellow so there is minimal (if any) energy transfer. A violet surface has intrinsically less energy (shorter frequency = more energy required to heat it up) so through the `osmosis' of light, violet heats up.

This is... MADNESS
