\mathrm{V= \lambda f}            \mathrm{V= \frac{C}{\mu }}
When the wave goes from rarer to denser medium speed decreases, the frequency remains the same, and therefore wavelength decreases.

As the number of waves per unit from one medium to another medium remains constant to maintain continuity.

\thereforeThe correct answer is (3)
