Jessica shines a lamp that emits a variable intensity light on a photoelectric cell. She notices that a current can be detected on the current indicator. When the lamp is turned on, no current is detected. Even increasing the intensity of the light t the maximum level has no effect.
Jessica repeats the experiment with a different lamp. When the lamp is turned on, no current is detected. Even increasing the intensity of the light t the maximum level has no effect.

(I think you've got the story muddled.)
If there is a current, it will be proportional to intensity. If you increase the intensity at any fixed frequency, you increase the number of photons but te energy of each photon remains the same.

it is thrilling The capability of the wave will advance. it relatively is infact a relative term between 2 waves of the same amplitude. If the amplitude of the waves varies for the same frequencies then the energies additionally variety. If the frequency is severe yet amplitude is low and the frequency is low yet amplitude is severe (or very severe for assumption sake), then the low frequency waves have extra capability. as an occasion the x-rays emitted from a CRT tude has much less capability whilst in comparison with the capability in a one thousand Watt loud speaker output or from that of a Tsunami or an earth quake. What a humorous answer??
