Question

एक प्रकाश विद्युत पदार्थ का कार्य फलन 3.3 हुई है उसकी देहली आवृत्ति क्या होगी​

Answer 1

$\underline\red{\bold{ANSWER}}$

$\underline\red{\bold{GIVEN}}$

• The work function (w) = 3.3

$\underline\red{\bold{FORMULA}}$

$• Threshold \: frequency(ν0) = \frac{h}{w}$

where,

h = plank's constant

$\underline\red{\bold{SOLUTION}}$

• Threshold frequency =

$ν0 \: = \frac{h}{w} = \frac{6.02 \times {10}^{ - 34} }{3.3} \\ \implies \: ν0 \: = 1.8 \times {10}^{ - 34}$

$\blue{\texttt{your answer}}$

Threshold frequency =

$1.8 \times {10}^{ - 34}$
