Rating: 4.0; Vote: 1
The microraptor was a four-winged carnivorous dinosaur with iridescent black feathers. But if our information about this dinosaur comes from fossils, how can we be certain about its color? Len Bloch shows how making sense of the evidence requires careful examination of the fossil and a good understanding of the physics of light and color. Lesson by Len Bloch

2: 24 Doesn't it also work for the case when the wavelength is twice the distance between the two reflections, because the wave travels that distance twice (once forward and another backward?
In that case it's also correct when the wavelength equals the distance between the two reflections, but you can construct all of the cases from the wavelength equals twice the distance case, where you can only construct half of the cases from the wavelength equals distance case (for anyone wandering, I'm talking about finding harmonics.

I always asked myself that! Good to know! I've never understood how all those dinosaurs had no feather, for example, the pterodactyl in Jurassic Park. I used to think that if some other beings ever found our bones, they would think we had no nose or ears.

This is about dinosaurs with feathers what about those who resemble reptiles eg T-Rex?
How can colour of their skins can detected

I feel like the dislikes are from cultists that are too closed minded to accept the overwhelming evidence of the dinosaurs existence

You didn't even tell us how sciencentist know what colors dinosaurs were. You told us about bird feathers bro. What the heck.
reply

how do you know dinosaurs are real? i think all of this is a fake, you guys should make a research about this, I got surprise
