Answer
It is not possible to eject electrons from titanium metal using visible light.
Work Step by Step
From this formula $$E=\frac{h\times c}{\lambda}$$
we see that $E$ and $\lambda$ are inversely proportional.
Therefore, any radiation with wavelength $\lambda\lt286.3nm$ would produce photons of energy $E\gt6.94\times10^{-19}J$, the minimum energy $(E_{min})$ needed to eject electrons from titanium surface.
In other words, to eject electrons from titanium surface requires a radiation with wavelength less than $286.3nm$.
The wavelength range of visible light is from $400nm$ to $750nm$.
Therefore, visible light could not eject electrons from titanium surface.
