Question 287: Dual Nature of Matter and Radiation

Question

The figure shows the variation of photocurrent with anode potential for four different radiations. Let $f_a, f_b, f_c$ and $f_d$ be the frequencies for the curves $a, b, c$ and $d$ respectively

Accepted Answer

We know stopping potential is directly proportional to the frequency of the incoming radiation. This means curve ' $a$ ' has the highest frequency and 'd' the lowest.
$$	herefore \quad \mathrm{f}_{\mathrm{a}}<\mathrm{f}_{\mathrm{b}}<\mathrm{f}_{\mathrm{c}}<\mathrm{f}_{\mathrm{d}}$$

Answer

$\mathrm{f_a>f_b>f_c>f_d}$

Answer

$\mathrm{f}_{\mathrm{a}}<\mathrm{f}_{\mathrm{b}}<\mathrm{f}_{\mathrm{c}}<\mathrm{f}_{\mathrm{d}}$

Answer

$\mathrm{f}_{\mathrm{a}}>\mathrm{f}_{\mathrm{b}}<\mathrm{f}_{\mathrm{c}}=\mathrm{f}_{\mathrm{d}}$

Answer

$\mathrm{f_a=f_b>f_c>f_d}$
