    Photoelectric Effect

    Does this show that light has wavelike or particle like properties? Why? What wouldthe results look like if they had only wave-like properties?

    What is the effect of increasing the intensity of a laser of a frequency lessthan thethreshold frequency?

    What is the effect of increasing the intensity of a laser of a frequencygreaterthethreshold frequency?

    Write the electron configurations for C, N,

    and O. Place in order of increasing ionization

    energy, increasing electron affinity and

    increasing electronegativity. For each

    characteristic, do these follow the trend?

    Why or why not?

    Wrong Answer 1:All: C, N, O

    Yes

    Because the trend goes up and tothe right.
