Question

Calculate the energy of photon of 3×10^5 HZ frequency .​

Answer 1

$\boxed{\boxed{\underline{\huge{\bold{\green{\mathfrak{Answer}}}}}}}$

Frequency given

$3 \times 10 {}^{5}$

Planks constant

$6.6 3 \times 10 {}^{ - 34}$

formula

$\huge{\bold{\mathcal{\purple{E=HxF}}}}$

$energy = 3 \times 10 {}^{5} \times 6.63 \times 10 {}^{ - 34} \\ energy = 19.89 \times 10 {}^{29}$
