Radiations of frequency 1.5 timesthe threshold frequency falls on aphotosensitive material and a photocurrent of I is obtained. If the intensityof incident radiation is doubled andfrequency is reduced of half, the photocurrent becomes |

Answer» If the frequency is halved and intensity is doubled the frequency if incident light become 1.5/2=0.75 time the threshold frequency .Hence photoelectric current will be zero |
