# Accidentally A Riley [first attempt]

This is my first time attempting to create a Riley Riddle. Feel free to give any suggestions.

My head travels constantly at the velocity of the product of setting ablaze.
My body is the head of a color, when the wavelength is DXC to 26C nm, they blaze.
My suffix, are the occurrence of hitting a surface, when they are rays.
What am I? When you get it, I hope you didn't just utter a random phrase.

Smock has already identified parts of it but I think the overall answer is

Coincidence

My head travels constantly at the velocity of the product of setting ablaze.

The speed of light in a vaccum is constant and denoted by c (already found by Smock)

My body is the head of a color, when the wavelength is DXC to 26C nm, they blaze.

DXC is 590 in Roman numerals, 26C in hex is 620 in decimal (found by Smock). 590-620nm is roughly the range on the electromagnetic spectrum corresponding to orange, whose head is o (also mentioned by Smock)

My suffix, are the occurrence of hitting a surface, when they are rays.

Incidence - in physics, is the intersection of a line, or something moving in a straight line, such as a beam of light, with a surface.

What am I? When you get it, I hope you didn't just utter a random phrase.

Is it a coincidence that we obtain the answer?

Title

Coincidental is synonymous with accidental

• Good job! As it's my first one it might not sound as good. I tried my very best to rhyme. – H_D Feb 15 at 2:17
