Answer:
"[tex]2.829\times 10^{31} \ photon/s[/tex]" is the appropriate solution.
Explanation:
The given values are:
Power,
P = 3.47 W
Frequency,
f = 185 Hz
Planck's constant,
h = 6.63 x 10⁻³⁴ J.s
As we know,
⇒ [tex]n=\frac{P}{E}[/tex]
Or,
⇒ [tex]n=\frac{P}{hf}[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{3.47}{6.63\times 10^{-34}\times 185}[/tex]
⇒ [tex]=\frac{3.47}{1.22655\times 10^{-31}}[/tex]
⇒ [tex]=2.829\times 10^{31} \ photon/s[/tex]
