Can you add a second fixture to a switch loop?

[Certain-Jacket-5244]

I currently have a light fixture on a switch loop and would like to add a second light that would be powered by the same switch. Can you add a second fixture? Forgive my novice picture, but if so, is this an allowable setup?

if you wanna installed second lighting included existing switch, that way is allowable.
