Aphoton and electron with the same frequency will also have the same

Explained

Explanation:

They will have same energy because

E=

where is frequency

h=planck's constant

as frequency is same and h is constant thus energy is same for both.

and they also share the same momentum

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
