Question

1 mole photon having frequency is 5*10 to the power 14 hz .
so energy is ?​

Answer 1

$\Large\underline{\underline{\sf Given:}}$

• Mole of photon (n) = 1 mole

• Frequency (f) = $\sf{5×10^{14}\:Hz}$

$\Large\underline{\underline{\sf To\:Find:}}$

• Energy (E)

$\Large\underline{\underline{\sf Formula\: Used:}}$

$\large{\boxed{\boxed{\sf \pink{E=nhf}}}}$

Here ,

E = Energy

n = mole of photon

f = Frequency

h = Plank Constant $\sf{6.63×10^{-34}\:J.s}$

$\Large\underline{\underline{\sf Solution:}}$

$\Large{\sf E=nhf}$

$\implies{\sf 1×6.63×10^{-34}×5×10^{-14} }$

$\implies{\sf 33.15×10^{-20}\:J}$

$\implies{\sf E=33.15×10^{-20}\:J}$

$\Large\underline{\underline{\sf Answer:}}$

⛬ Energy of photon is $\bf{33.15×10^{-20}\:J}$
