व्हाट हैपन टू द फोटोइलेक्ट्रोंस वन इंस्टिट्यूट इंटेंसिटी ऑफ इंसिडेंट रेडियन बी फ्रीक्वेंसी ऑफ इंसिडेंट रेडिएनसिस इनक्रीस ​

Answer 1

Answer:

Maximum K.E. of the emitted photoelectron is given by

<br> From above relation we not that if

is more, then

is less and vice versa. <br> (a) If the intensity of the incident radiation is doubled, <br> (i) the stopping potential remains unchanged <br> (ii) the photoelectric current gets doubled. <br> (b) If the frequency of the incident radiation is doubled, <br> (i) then the value of stopping potential becomes more than double as explain below: <br>

<br> and

<br> or

<br> or
