"Is there light at the bottom of the ocean?"

Translation: Apa ada cahaya di dasar samudera?

[StephenL1]

is there always an "e" in samudera? I've seen it spelled samudra, is this also correct?

'samudra' is the new official KBBI spelling.

Would "Adakah cahaya di dasar samudra?" work in this instance or no?
