Final answer:

The query involves calculating the binding energy of titanium using the photoelectric effect equation, with known kinetic energy of ejected electrons and the wavelength of incident light.

Step-by-step explanation:

The question is asking for the binding energy of titanium when it releases electrons upon irradiation by light with a specific wavelength. To find this, one would typically use the photoelectric effect equation:

Energy of photon (E) = Binding Energy (BE) + Kinetic Energy of ejected electron (KE)

In this case, the kinetic energy (KE) is given, and the energy of the incoming photon (E) can be calculated using the formula E = hc/λ, where h is Planck's constant (6.626 x 10-34 J⋅s), c is the speed of light (3.00 x 108 m/s), and λ is the wavelength of the light. Once you have both the KE and the photon energy, you can rearrange the equation to solve for the binding energy (BE).
