Which of the following frequencies corresponds to light with the longest wavelength: 8.50 times 10^20 s^-1 9.12 times 10^12 s^-1 3.00 times 10^13 s^-1 4.12 times 10^5 s^-1 3.20 times 10^9 s^-1 Yellow light can have a wavelength of 572 nm. The energy of a photon of this light is 2.88 times 10^18 J 5.72 times 10^-7 J 5.24 times 10^14 J 3.47 times 10^-19 J 1.14 times 10^-31 j When light strikes the surface of a metal with a frequency BELOW the threshold frequency, are not emitted emitted with a energy equal to the light's intensity emitted with a energy increasing linearly with the light's intensity emitted with a energy decreasing linearly with the light's intensity none of the above The four lines observed in the visible emission spectrum of hydrogen tell us that: We could observe more lines if we had a stronger prism. The spectrum is continuous. The hydrogen molecules they came from have the formula H_4 Only certain energies are allowed for the electron in a hydrogen atom. There are four electrons in an excited hydrogen atom.
