**1. Homework Statement**

Electromagnetic radiation of wavelength λ and Intensity I, when incident on a metal surface, causes n electrons to be ejected per unit time. The maximum kinetic energy of the electrons is Emax.

State and explain the effect, if any on n and Emax when the wavelength λ is reduced but the intensity I is unchanged.

**2. Homework Equations**

E=hf, and I'm not sure what else

**3. The Attempt at a Solution**

I solved this question with 2 different teachers, the first said that n will not change as I is unchanged. The other said that n will reduce because:

number of photons=Intensity/energy of 1 photon

I trust both teachers so I'm really confused now.
