PLEASE HELP ME WITH THIS ONE QUESTION During the photoelectric effect experiment, a photon is emitted with 9.60 x10^-20 J of kinetic energy. If the work function of the photosensitive surface is 1.68 eV, which is the frequency of the incident light? (h = 6.626 x 10^-34 J·s; 1 eV = 1.60 x 10^-19 J)

Answerigneous bedrock of the oceanic crust;

The correct option is this: the sound waves from the two trombones have slightly different frequencies.from the question given above, we are told that the loudness of the sounds were increasing and decreasing, this is because the frequencies of the two sounds are different. the means that the number of waves that pass a fixed point in a given amount of time differ for both sounds.
