1. The problem statement, all variables and given/known data
True or False question
5. If a Young’s double-slit apparatus, having operated in
air, were to be submerged in water, the fringe pattern
would become less spread out.


2. Relevant equations
c=f(lamda)


3. The attempt at a solution
What i think they mean: does the wavelength become shorter when light is traveling in a slower medium?

What i don't know is does the frequency of light stay constant regardless of the medium?
If yes, then the statement is true.

Yes, the frequency is constant regardless of medium. The frequency of a wave only depends on the oscillations of the source of the wave.
