Which theory was contradicted by experiments with the photoelectric effect? Light spreads out after it passes through a small opening.

As soon as light strikes metal, electrons will be ejected.

Visible light, regardless of color, will cause the ejection of electrons when striking metal.

The kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

Bohr's model could only explain the spectra of which type of atoms? single atoms with one electron single atoms with more than one electron bonded atoms with one electron bonded atoms with more than one electron

Consider the following system at equilibrium. caco3(s) ca2+(aq) + co32–(aq) the addition of which compound will cause a shift in equilibrium because of a common ion effect? ccl4 co2 cuso4 na2co3

Which statement best describes the relationship between period and frequency of light waves? a) in wave b the period increases and the frequency decreases from wave a. b) in wave a the period increases and the frequency decreases from wave b. c) in wave b the period is shorter and the frequency is greater than in wave a. d) in wave a the period is shorter and the frequency is greater than in wave b.
