(c) Potential difference between the emitter and the collector
(d) All of these

Answer 1

Answer:

all of these option (D)

Explanation:

today in my quiz also I got it

Answer 2

Answer:

In the photoelectric effect, the maximum velocity of electron reaching the collector is determined by the frequency of the incident radiation(ν), on the work function (hν₀), and the potential difference between the emitter and the collector.i.e.option(d).

Explanation:

First, let's understand what is the photoelectric effect.

" The phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation".

The photoelectric relation is given as,

$h\nu=h\nu_o+K_m_a_x$           (1)

$K_m_a_x=\frac{1}{2}mv^2_m_a_x$

$h\nu=$incident energy

$h\nu_o=$work function

We can rewrite equation (1) as,

$h\nu-h\nu_o=\frac{1}{2}mv^2 _m_a_x =eV$     (2)

From equation (2) it is clear that the maximum velocity of the electron reacting at the collector depends on the frequency of the incident radiation(ν), on the work function (hν₀), and the potential difference between the emitter and the collector.

Hence, the correct option is (d).
